Finding Capacitors
5/1/2009 5:19:00 AMJesse Hancock
This is driving me nuts ! I cant find the caps Im looking for online. Does anyone know where you can locate close to exact values found in a Radio? Ive checked MCM, and all the other online sources and trying to find the right values.. Im stumped.

Post the actual value and voltage here and someone will point you in the right direction.

Hi Jesse

Both AES, www.tubesandmore.com and Radio Daze, www.radiodaze.com sell caps and other parts for radios. Just Radios is a good supplier for caps, www.justradios.com .

:Hi! Jessy,
For a beginner, capacitors can be very confusing but if you go to www.justradios.com website, as Norm suggested , you will find a heading called "capacitor tips". Here you will find a great deal of info on capacitors and it is free.If you google the, ( Phil's Old Radios),site follow the links and click on the "beginner" heading, there is a load of info on old radios and it is free. There you will find the section "why and how to replace capacitors" ,which has a full explanation and pictures of various capacitors used in old radios. I printed the info from both sites and put it in a folder so that I can refresh my memory from time to time.Hope this helps. Bob Masse

5/1/2009 5:05:41 PMdave at just radios will put a kit together
just send an email to dave at justradios with your model number and he will send you a kit specifically for your radio. nice and easy to deal with chap

Could you perhaps be trying to match values that are no longer produced ?

For example.....trying to find a .05uf cap, which was a common value 50 years ago,is pretty tough. Nowadays this value is replaced with a .047uf cap, etc., etc.

Except for tuned circuits, capacitor values are seldom critical. Use at least the rated voltage of the original capacitor. Except for electrolytic, capacitance values within plus 50% or minus 20% of original is still very conservative. (I go larger than original; set manufacturers tended to use the smallest / cheapest capacitor they could.) Electrolytics should be the original voltage rating, or the next highest available; up to 100% over the original capacitance value will seldom cause problems. However in a power supply with choke and / or field coil choke, check voltages carefully, as a value different from plus or minus 30% may create a resonant situation, and result in instability or overvoltage.

Hi Jess

What values are you looking for?

Exact values aren't critical. Old value of .05 mf has been replaced by .047 mf. You can always use a higher voltage rating. 600 volt caps will replace 200 or 400 volt rated.

For filter caps 10 mf can replace 8 mf, 22 replaces 16 or 20 mf.

Dave at justradios can get you what's required.
