Finished the right power amp and the power supply. Glad I verified the transistor orientation with my meter. I almost put them in bass ackwards. So far no smoke and it still works. Still has an annoying hissing sound but I'm sure will get this eliminated by the time I'm done.
SX-1010 Rebuild BOM help
- Thread starter 5yearplan
- Start date
I have replaced everything on the list except the transistors that attach to the heat sinks on the power amps and the power supply. Im still waiting for some to be delivered. I haven't had any issues yet other than it still has a hissing noise or hum. The noise goes away if I pull the pre amp jumpers from the back panel. It is equal both sides and goes up with the volume. If I ground the case it almost disappears so I measured from the case to ground and get 60V AC. Has anyone had this before?

Mouser currently has the 863-MJE15032G on backorder. Is there an alternative transistor or source for Q1 and Q7 on the power supply board?

I looked on Digikey. Is this the same thing?

I'd hate to split up the order for one transistor.
