Hi. I picked up a rough SC Stereo 60 recently. Powered it up slowly with a variac, and got sound through Aux and Tuner inputs. I didn’t check the phono or tape head inputs. So I then recapped the electrolytics and tubular caps. Restuffed the 20/20/20/20uf can cap. The Aux and Tuner inputs sound great. But the phono and tape head inputs don’t. I can barely hear audio signal coming through one speaker. Tried different 12ax7 tubes. I think I may have a wrong connection on the can cap, even though I took pictures before I started. ... lol. I’m looking for the 75 vdc on R78 & R79, but I’m only getting around 30 vdc.
I have R80 (150k) connected to the negative can cap. Is this correct?
I have R70 (3.9k 5watt) connected To a positive can section. Is this correct?
Any and all help is greatly appreciated. Thanks for reading
