Hi All
Just bought a Pioneer RG-1 and it is not functioning well at all. Power and lights come on good. Both meters bounce well and evenly when given signal (turntable via tape loop). Left channel no sound. Right channel very weak sound. Plan is to change out all 20 of the transistors as well as any out of spec Caps if I can find modern equivalents in hopes that it will rectify the issues. Have service manual so plan to do transistors first as I hear they are the more troublesome offenders.
Looking for a list of substitute transistors to change out the 22 listed transistors as per images attached. Wanted to know if anyone can tell me if the following mouser PN substitutes are OK?
2SC1312-F with 512-KSC1845FTA
2SC945-Q with 512-KSC2383YTA
2SC1384-R with 512-KSC2073TU or 522-ZTX694B
2SA684A-R with 512-KSA1013OTA
Thank You for any advice
