As can be seen, some of the chokes in the bottom have not done well. Two of these have broken terminals and cannot be safely repaired. These are 10H 0.45A chokes. (Donations are needed and welcome!) These chokes are in series with the PA power supply output and the B+ end of the modulation transformer. Other things you see are one of the the rectifier filament transformers, a Chicago FV-520H, 5VCT, 20A, 9KV insul.,(center), two of the 575A rectifier sockets above it, top right - the corner of one of the modulator filament transformers, bottom - the top of one of two 'pole pig' plate transformers. To the left of the rectifier sockets is a 0.0015uF capacitor connected between the modulator tube plates.
