Hi all, im working on this set, line resistor was found open on the short section, this has part # 6124 three connections and is a wire wound resistor in a metal sleeve that is riveted to the chassis for heat sink purposes I think, was able to find a good one out of a part chassis. My next problem is how close to the values can I go with replacement paper caps, i need a .15 mfd but i have a .1 and my next available is a .2? I forgot how tedious those small radios are to work on, just all components are packed in so tight, lots of coffee and patience, long tweezers help too!!!!

Either one will work OK; but as a general rule, when in doubt use a higher-value cap (not to exceed 100% of the nominal value).

Ah ok, my thought was going a bit higher, just didnt know how much was acceptable, in this case 25% is all good,
Thank You

All done recapping and installing replacement resistor, now found 2 tubes with open heater filaments so the search is on for some good tubes!

You can come very close to the required value by connecting two capacitors in PARALLEL. The overall voltage rating will be whatever the lowest rating of the pair is.

i.e. > .1uf(@400v) + .047uf(@630v) (wired in parallel) = .147uf total capacitance (@400v) ..... pretty close to the .15uf requirement.

Thank You Dennis, adding extra components in this chassis is pretty difficult, real estate is not there, although the new caps are typically a lot smaller, I found another big blunder, previous person installed a 35z5 tube instead if a 35z4, probably what burnt out that resistor and possibly those 2 other tubes,

The 35Z5 will probably work ok. Would just make sure there was nothing connected to pin 3 of the tube socket.

:yes thats exactly what happened, pin 3 was being used as a connection point and it shorted out a section of the heater string causing over voltage to the rest of the tubes
