Hi guys. First post/question because I have managed to find answers to all previous questions from earlier posts. With your help, I have restored/recapped a Marantz 2235B and a Sansui 6060 that have been needing attention for years. So thank you very much for making this hobby so fun and rewarding!
I recapped all the Sansui 881 boards except the AM/FM sections. I changed the four output transistors to MJ21194Gs; the originals tested OK but I wanted new (so maybe this is my problem). Bias is set according to the manual. DC offset is also set according to the manual, and on the low side - around -8mV.
The issue is that I get speaker pops and SMOKE from board F-2436 on startup when speakers are attached.
The unit sounds great and I haven't found any other problems. Any advice would be greatly appreciated. Thank you
