Hello...Posted a while back about this receiver. Life got in the way, yada, yada...I re-capped it and changed some problematic transistors. I checked the voltages on the boards today (see pic's) they seen ok, on the power supply board the output pin 5 says 78V (64V) got 82V, pin 6, 35V have 41.0V, pin 8 125V have -0.060 and pin 11, 23V have -0.060V. Now on pins 9 and 10 on the input for the board the readings are the same. I'm lost about this. Everything else looks good. I'm starting the hunt board by board to trace the signal with my multimeter and Rigol DS1054Z oscilloscope (what a learning curve that was and it's still smarter than I am). I've checked the boards for mistakes, caps put in backwards or a cold solder joint(s), I've checked a half dozen times and have found nothing. It's been a while since I've used a solid state receiver, is there supposed to be a click after it's turned on or not? I'm referring to the circuit protection. There is no click but the slightest pop in the working channel. I've looked for the circuit protection on the schematic, not sure what it is or where it's located. I'm splashing around in the deep end of the pool and learning a lot. If you've worked on one or have any ideas or input please let me know. Thank you.
