philco model 16
#5

when i got the radio a capacitor was bridged across the choke , there was one other i think mistake a capacitor .o5 was bridged from end of resistor 92 140 ohm end to speaker plug terminal that connects to resistor 90 7,750 ohm . when this radio was first turned on like this it didn't work and looked odd tube 80 glowed purple no other tubes lit i turned it off in 20 seconds. i later disconnected this ( the capacitor .o5 bridged in this spot ) and tried it again borrowing the part 97 from another model than it lit one tube ( on this second try i had variac so it was only powered to 90 v. one tube no. 78 rf lit but no others the purple tube problem was gone. i'll have too return this part to the other radio i hope though if i try it again i can get more filaments lit i wondered if people had changed any wiring around the 73 capacitors
