Philco 16B 5 band Code 121 Help Please
#4

I was not able to measure all the voltages because it is very hard to get at the pins but below is the list I was able to get at. What I see is that the Cathode of of the 1st IF is very high at 37 Volts. I hope this helps.

2nd IF - #78
Plate 220 Volts
SG 110 Volts
K 3 Volts

1st IF - #78
Plate 218 Volts
SG 110 Volts
K 37 Volts

Osc - #76
Plate 71 Volts
K 2.6 Volts

1st Det - #77
Plate 217 Volts
SG 110 Volts
K 6 Volts

2nd AF Driver #42
Plate 207 Volts
SG 207 Volts
K 0 Volts
