Is there an update to this list....it is 8 years old....

Michael in Florida

Maybe I’m having a senior moment here but need to clear this up. Anyone out there please confirm…. When holding the capacitor, and transferring signal to its most outer plate (shell), than the signal lead to the oscilloscope being larger would be that side to be grounded, or come from the plate of a tube, Banded side. Right?

Clifton Schlicher

Your reference to the 'verified parts list' implies there is a list of other parts beyond capacitors. If there is, could you location to find it? Thanks

KC

An update regarding this list you might want to make — Rubycon 450TXW47MEFC16X25 is not a current number. The current part would appear to be 450TXW47MEFR16X25. (Note the R in place of the C.) Rubycon also has a newer series which includes 450BXW47MEFR16X25 which has twice the ripple current rating for just a few pennies more per cap. The other specs look the same. Also, Jay, please check this component in your mouser cart. You have a PK one there, and that is not the same animal.

LoSaYa

Thank You For the great info.

Tim

Thank you for that Jay. Much appreciated. Same appreciation to Mr. C.

Jay Cronen

This is the exact parts list and nothing more: https://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=32a5c4d222

Another awesome video! I am going to get stocked up on these parts for the restorations and repairs bench. Thank you very much.

Ryan Dunbar W1RMD

I've seen on lower value (like .015 uF) polypropylene capacitors have very little difference between the foil and "non foil" ends. Too little to tell. MUCH more obvious with say .022 uF and larger caps. Also, I can't find any good answer to if you have an audio amp with a capacitor in series with the input connector which way the foil side should go. I assume that the input is the lower impedance, but wouldn't the foil out pick up noise also? Great video and tool also.

Halfhorse

I just ordered 15 of each on the list. Mouser had them all in stock and the cheapest price. When they get here I have a Zenith as my first tube restore project.

Sprocket Tinkerwind

The LED is inverted to the way we usually think. It is showing "ground" not probe. If the foil is 'grounded' it shows a lower signal on the scope because the noise is going to scope ground. If the internals are "grounded" (it's LED is lit) then the probe wire is connected to the outer foil and more noise is shown. If he had wired it up so the LED shows the probe connection, then Higher signal= outside foil.

Daniel

Glenn, I think your reasoning is correct (I am new to this, so take it with a grain of salt). The outside foil is connected to the center lead of the coax cable when the light is OFF om that side. If the hum is HIGH on that side, it means that this side is the outer foil. Looks like this approach is inverted where we look at a LOW hum on the side that with the led ON (tied to ground). I may not understand this correctly, but I would have used the ON state for the center and hum HIGH as indicator, essentially inverting the light signal and the scope reading. Does that make sense or am I missing something here?

Glenn Hooper

I have watched this a few times. I must be having a senior moment. By holding the capacitor, inducing noise to the outside foil, wouldn't the larger noise shown on the oscilloscope be the outside foil? In my mind, the inside foil (being protected from the outside foil) would show the smallest signal.

Robert McDermott

Question about a resistor assortment. Seems like 1/2 watt carbons are the rage in old sets. Can I buy a large 1/2 watt Chinese set off AMAZON ? Are they any good ? They are not carbons I guess, But does that matter in circuits, As carbons vary over time ?

Murat ERAYDIN

Looks like you have bought all the WP424QR51WT/D-AMT (blue led) in the world :) any alternative?

Jimmy Moore

Shane, it looks like RG-316

Shane

Paul, do you mind sharing the info on that coax cable? It looks great, I see you've used it in a lot of builds. Can't find the info on here. Thank you,

Allen Haswell

no... because the 2 channels share a ground....

Brian Mathews

If you had a 2 channel scope could you hook the probes with one set opposite and determine which set was on the foil?

Rick kennard

If you have to choose between a lower or higher capacitance for replacement parts, is it better to go one way or the other?

Bruce Dow

Wow! I can't tell which of those two Vishay capacitors is real and which one is printed on the paper! Haha

Mr Carlson's Lab

Hi Roger. Those Solen capacitors are good. I haven't tested any on the forecast position of my newer cap tester, but I imagine they would pass.

ROGER BRUMLEY

Mr. Carlson thank you for the capacitor list. my Mouser order just arrived today. i found some on ebay the brand is "Solon" from France. I was wondering if you have ever heard of or tested them before? they have some with good values .01uf @ 1000vdc and they are Metalized Polypropylene. here is a screenshot of them...<a href="http://prntscr.com/ka14vz" rel="nofollow noopener" target="_blank">http://prntscr.com/ka14vz</a> have you seen them or tested in the past? thanks for your time.

Wayne Thompson

I have noticed a number of times that you have "gobs" of components, some just bulk, some tape and reel type, etc. To say I have been jealous would be an understatement. Rather than hang on to that, I wonder if you could provide a source where these items could be purchased in bulk at a "poor man's" price?

Jim McCusker

Here's a good video showing a similar way to test for this using an audio in to your computer. The guy made his own box to switch back and forth between tip and ground. You can do this by simply downloading Audacity (Windows/Mac) and creating the necessary audio input cable for your audio card. BTW, I take no responsibility if this frys your sound card. Here's the video demonstrating how it works. <a href="https://www.youtube.com/watch?v=J_myAR9TO0g" rel="nofollow noopener" target="_blank">https://www.youtube.com/watch?v=J_myAR9TO0g</a>

Mr Carlson's Lab

Hi Peter, just newer ingredients and assembly techniques. Poly is poly.

Peter Sage

Aren't the Illinois polyester capacitors virtually identical to classic Mallorys? Also, instead of (or in addition to) the dot, I'd crimp the outer foil lead to build in a little thermal stress relief.

Stelzi79

Is there an easy way of detecting the outfoilend without an oscilloscope?

Mr Carlson's Lab

Thanks for your input Mike!

Mike R

Thank you Jordan for the list it's a real timesaver.Mr. Carlson I was thinking something that would really be helpful to people like myself were just getting started in electronics.A list of commonly used components. To build up a supply so when not searching for each project. Not suggesting you source them. Just a list for us to hunt down. That's part of the learning process. Mike R

Mr Carlson's Lab

I think so, but here's the thing, IC is a great name and you know the facility is good.

scott palmer

I ordered 10 each from the list. Is everything made in China now?

Mr Carlson's Lab

Thanks for taking the time Jordan.

JordiSnowman

I created a Shopping list on Mouser.com with all these parts included. Go to <a href="https://www.mouser.com/Tools/projectcartsharing.aspx" rel="nofollow noopener" target="_blank">https://www.mouser.com/Tools/projectcartsharing.aspx</a> and search for this identifier "5a721a8734" and anyone can access it or buy it. 10 0f each item is about $116.16 U.S. plus shipping, 100 of each is about $900 or so.

Mr Carlson's Lab

Hi Steve. I made some "Break out" boards for smaller components. Basically just make some small PCB's with a single component pad arrangement and add some lead out wires.

Steve Jones

I saw on your ft1000 repair video where you had a surface mount transistor on a breadboard, where did that transistor assembly come from?

Larry { N7LUF }

This cap 566KXM050M , I would have to ordered 3000 of them but digikey has it in 493-1897-ND Nichicon cap, are they any good?

Larry { N7LUF }

I want to recap a Yeasu FT-736 power supply and part list I have is for Panasonic Industrial Devices and from digikey. Here is the part list url <a href="http://www.qsl.net/w2aew//youtube/FT-736R_Replacement_Capacitors.pdf" rel="nofollow noopener" target="_blank">http://www.qsl.net/w2aew//youtube/FT-736R_Replacement_Capacitors.pdf</a> and <a href="http://www.qsl.net/4/4x6on/RADIO%20MANUALS/YAESU/YAESU--FT-736R-PS-Repair.pdf" rel="nofollow noopener" target="_blank">http://www.qsl.net/4/4x6on/RADIO%20MANUALS/YAESU/YAESU--FT-736R-PS-Repair.pdf</a>

Mr Carlson's Lab

There are others as well Larry. I find that over the years, I have never had an issue with them.

Larry { N7LUF }

Am I hearing that "<a href="http://www.digikey.com" rel="nofollow noopener" target="_blank">http://www.digikey.com</a>" is the only place one should buy parts from safely?

Zexufang

Thank you. Lesson learned. So many more to go.

Rodney Garrett

Thanks Paul I will try that. I found a site in Canada justradios for the capacitors.

Mr Carlson's Lab

Hi Rodney. The community section is a great place to ask questions, just start your own post... you can add pictures too! The resistor is very close to 10 Ohms. If you have a way to measure resistors with good accuracy, test a whole bunch of 10 Ohm resistors, your bound to find one that measures 9.7 Ohms.

Rodney Garrett

Not sure if this is the correct area to post a question like this. Let me know if I need to move it. Thanks

Rodney Garrett

I am trying to rebuild a EICO model 232 VTVM. I want to change the capacitors and I know that one precission resistor is burnt out. It's value is 9.7 ohm 1/2 watt and 1% .Am I going to be able to find a replacement? Some of the caps I need I looked for on Digikey but they didn't have them. Any Help?

Rodney Garrett

Helo,

Hunter carmouche

Made my order with DigiKey. Seems they were out of the .1's. I'll get 'em from Old Radio's.

Eddie Bray

Get yourself a Digikey and Mouser account, in the UK, provided you spend more than £33 before vat shipping is free, there are also no customs fees or duty to pay as they take care of that their end. They are remakably quick too, I placed my last order 21.40 on a Monday night and it was delivered at 12.15 on the Wednesday.

Diabolical Artificer

Illinois caps are trickier to get from UK supplier's and can incur an extra delivery charge of £15 from Farnell as they come from the depot in France. I use these - <a href="http://uk.farnell.com/vishay/mkt1813310635g/cap-film-pet-10nf-630v-axial/dp/1166871" rel="nofollow noopener" target="_blank">http://uk.farnell.com/vishay/mkt1813310635g/cap-film-pet-10nf-630v-axial/dp/1166871</a> made by Vishay. Ero caps are decent too. I find the results when testing for the outside foil a bit ambiguous sometimes, even with the scope on 1mV/div.

Mr Carlson's Lab

I do agree.

Dacke

I actually have some of these yellow tube style Illinois Caps I got from Digikey a while back. The only downside is that they are expensive. Same with Vishay. Excellent video though Paul! Also I'm going to plug Digikey here, it is really the only place that I haven't had counterfeits or cheap crappy components. You will pay full retail for parts though, so it's better to order in bulk if possible.

Dacke

That means that there are two capacitors at 500 microfarad inside the can. Each shape represents a separate capacitor. For example, I have a few cans that have four capacitors inside them, with one terminal marked square, another half circle, another triangle, and the last one is a line. Each one should also have a voltage rating. The can itself is the negative connection.

Steve Young

Paul, First thanks for all your videos. I have an old car AM radio that I figure no big loss if I screw it up while learning about it. My question is that it has an old aluminum shelled capacitor marked with 500 MFD twice 1 has a triangle and the other has a square. These markings are also next to each post on the bottom of the cap. What do they represent ? Thanks.

Mr Carlson's Lab

Many future projects will have B+. This goes for the videos here, and on my normal youtube channel.

Mr Carlson's Lab

No problem Rod! :^)

Mr Carlson's Lab

You're welcome Carl!

Mr Carlson's Lab

You bet!

Mr Carlson's Lab

You're Welcome Marek!

1-800-STUPID

The parts you listed are rated at 400+ volts. Are your future builds going to require a high voltage power supply or direct mains supply?

Mr Carlson's Lab

No problem George!

Mr Carlson's Lab

Thanks Ralf!

Mr Carlson's Lab

Definitely a video there. I could write a book about this.

Mr Carlson's Lab

Not to push digikey or anything, but I find they sell good components... (haven't had any counterfeit's yet)

Mr Carlson's Lab

Hi Dave, that should get you started. Many of the projects that use those capacitors are "spur of the moment" over here. So I never know myself how many caps are needing replacement until I open up the unit. You will find each project is different, and many manufacturers just use caps they got a 'good buy" on. So, one project may use ten .01uF caps, and another may use twenty.

Mr Carlson's Lab

Hard to say Steven. There are so many counterfeit capacitors on the market today, one has to be pretty careful. Oddly enough, some of the older orange dips get leaky! I really think some of it is just environment, and bad quality control. I would test your orange dip caps for capacitance and leakage. Usually the counterfeits show really low for capacitance, as they skimp on material.

Mr Carlson's Lab

Thanks for the kind comment Bruce!

Steven Munts

Paul: I am interested in learning more detail about how you define and determine "really good" for a component such as capacitors and resistors? Are there a set of parameters, tests and minimum specifications that you could share with us, so that we might learn how to judge parts that we already have on hand? Or is the subject sufficiently deep that it would be worth a video? Thanks

David McAnulty

Is this for the course, or just for your regular youtube videos. If for course about how many should we buy (to follow along)? I just put quantity 10 for each into digikey (<a href="http://www.digikey.com/short/qc3cbr)" rel="nofollow noopener" target="_blank">http://www.digikey.com/short/qc3cbr)</a> and it's $90. I'm willing to spend the money, just wanted to make sure I didn't get ten 0.47uFs when I really needed twelve .01uFs

John Fitzgerald

Looking for the best place in the Toronto area to buy components?

Steven Munts

I have a question for Paul, but I am also interested in the thoughts of others as well. Paul, are "Orange Drop" capacitors considered as good as the ones you listed? Or does it depend upon the source of the Orange Drop? I have noticed several antique radio restoration parts supply web sites that advertise the Orange Drop capacitors. They generally offer them in a quantity for each of a number of capacitance values. Before I found your YouTube video's, I purchased some from one of these shops. Now I am wondering if I wasted my money and should discard them. Any advice would be appreciated. Thanks

George Myers

Thanks for taking the time to check and post.

Marek Tomczyszyn

Great tip Paul, thanks!

Bruce Havourd

Paul, you MIGHT consider opening up a branch of Amazon.com for yourself... just stock the GOOD stuff! We'll all buy whatever you stock... believe it! LOL

Reb Elba

You're right Anders this is also a valuable note! I made the mistake and mixed up quality with quantity. Some of the cheap Elko's are already bulging and all of the LM337 I got from the Bay are faulty. Lesson learned :D

Reb Elba

Very good advice, many thanks Paul! From my experience I don't get all the parts from stores in my country like Reichelt or Conrad. Mouser or Digi-Key are good alternatives but I have to keep an eye on the shipping cost's :)

Anders "SM7HCE"

And one thought that came to me... GUY´S !!!!, please be careful if you browse E-bay, web etc.. especially when it comes to electrolytics, .....good Caps ARE expensive, so it´s always a good practice to choose known brands from the beginning so you dont get bad habbits from the start :-), Have a wonderful day all of you.. /A

Anders "SM7HCE"

Nice move Paul, i dont want to do any advertising aswell, but i nowdays always use justradios.com´s capacitor kits when restoring any old tube cirquit ... atleast when it comes to Metalized Polypropylene.... i find that they are pretty ok ....one nice thing with them is that the original values are available even if it doesent matter much if a cap is 50 or 47, .... there is quite some tolerance in the old stuff :-):-)
