Hello everyone I am doing some preliminary research on what things I need to do a full rebuild on a working SX-1050. I have read in past threads that output transistors need to be matched.
MTF has previously suggested that using new modern output transistors will in fact be better than using the stock Pioneer ones that came from the factory. IIRC the stock ones don't have as clean output as the modern transistor.
How does one go about logically gain matching output transistors without a scope ?
The transistors that were suggested to be replaced in quads are
Brand:ON semi
863-mj21193g PNP
863-mj21194g NPN
Does matching infer that I simply replace all 8 at the same time or to replace transistors such that they are all made from the same batch by the same manufacturer?
What happens if I accidentally install one backwards and blow it up? Do I have to replace ALL outputs at the same time again or can I just buy the one that I fry (hopefully that never happens).
Thanks
