Anybody here experienced recapping old tube radios and such?
« on: January 01, 2018, 01:08:25 PM »
I always get top notch advice here, so at the risk of being greedy, here I am back at the well.

I'm thinking of recapping a vintage 1950s radio, but I can't read the cap values.  Here's what they say:

2 x Paper & wax:

AEROW (brand)
CAP 0.05 type 684 DCWV 600
CAP 0.02 the rest of the writing has worn off

3 x electrolytic

40 MFD 150 WV 200 PV, number 7 in a circle, 108
a pair of: K-65J365-38, 200-10 DC, number 2 in a circle, 303 15613217


Well, that's about it. I figure those first 2 are 50 and 20 nf at a 600 volt rating (sounds crazy high, no?).
The electrolytics are harder.  The one is obviously 40uf at - to be safe - 200 volts.  That pair is... a mystery to me.

I tried using my multimeter, but it didn't really help things.

Someone will ask if I have the schematic.  I don't and I can't locate it online.

The radio is a GE model C605, 115 volts, 0.2 amps.  It's Canadian.

As always, thanks in advance for any help - you guys are the best.

50nF at 600V, 20 nF at 600V (fairly standard for tube circuits)

40uF at 200V, 10uF at 200V (pair)

Good luck :)

Schematic on page 3.  Nostalgiaair is still the best source for old schematics.
