First post! 48-200 Code 121 differences?
#2

Well, we're glad you joined in on the fun! Icon_biggrin

Very interesting. I see production of the 48-200 and 48-214 began with Code 125 instead of the usual Code 121. In the prewar days, Philco radio production usually began with Code 121 and then went up. In this case, they began with Code 125 and then went back to Code 121 later.

Anyway, from what I found in a quick search, the only differences between codes 125 and 121 are the output and rectifier tubes. And then there was a Code 122 which used a different oscillator coil.

Long story short...C302 should be 0.1 uF. This is the AVC filter, and in many sets this cap is .05 uF so this may be why some repairman installed a .05 uF cap. Or maybe that's all he had in stock at the time, and it made the radio work again.
