First Radio Resto - Philco 60B
#26

I just finished up replacing all of the capacitors in the bake lite housings.  3903-AP did not make sense, it's replacement part is 3903-OSU which is a .01 uf between pins 1&3.  My 3903-AP clearly had the capacitor between pins 1&2 so that is how I wired the replacement.

I must have done something wrong.  The radio powers up, all tubes glow and there is a soft hum coming from the speaker.  The volume and the tuner dial effect nothing, hum remains constant.

While working on condensor 7 (3615-AJ) I must have broken the solder joint to the resistor leading to condensor 30, easy fix and every other connection appears good.

Any suggestions on areas to start troubleshooting?  I'm good with a multimeter, decent with schematics and fair/poor with radio theory...

Thanks for any help,
Matt
