Restoring a Philco 71 Code 121-No sound
#20

Electrolytics and safety capacitors I replaced. There are some paper caps still remaining soldered outside the filter capacitor metal box (P/N 21).
Evident that previous repair bypassed restuffing. I will attempt to rebuild that component but was trying to avoid a "shotgun" approach to replacing components. Thank you for your reply. I have a lot more work to do. Have not decided to rewind the oscillator coil until someone can corroborate my previous post for what I believe is the mapping.
