Hello
I'm repairing an old Yamaha M80, one channel is in protect mode. A lot of components are broken...typical in this model. I have found some of the damaged parts, but I have problems with some of them. This is the list of the damaged transistors:
TR132,134: 2SC773 -> Found (used)
TR136,138: 2SA1169 -> Found (used)
TR120: 2SC3298 (B) -> Not found. Replaced by 2SC4793 (old stock)
TR126: 2SA1306 (B) -> Not found. Replaced by 2SA1837 (old stock)
TR118: 2SC3416 -> Not found
TR124: 2SA1352 -> Not found
TR116: 2SC1953 -> Not found
There are some generic versions (not originals) of TR118, 124 and 116 in ebay. Are these transistors reliable? or would it be better look for a modern replacement? Any suggestions are greatly appreciated.
Please excuse my poor English.
