Hi Guys,
I’m in need of some help with a Zenith 7s488. I’ve recapped the radio and have the audio section working. I’m getting some bad voltage readings from some of the tubes. These voltages were recorded at 80 volts on a variac.
6K7G (RF)- P 205 v., G2 0 v., G3 0 v., G1 0 v.
6A8G (Converter) - P 0 v., G2 235 v.
6K7G (IF) - P 213 v., G2 0 v., G3 0 v.
6J5G (Det) - G 0 v.
I didn’t include readings from the 6X5G, 6F5G and 6F6G because they are apparently functioning. Transformers and coils show continuity so I assume they are good. This is a tough radio to work on because everything is packed tightly. Any direction from the Phorum Pfolks is appreciated. Thanks. - Rob Q.
