I acquired a pioneer sx1010 it had no sound on left side. I put it on the dim build tester and bright turned it off removed b539 light went dim and one I tested replaced them with mg21193 plugged it back in with the dbt bulb went bright again.
This machine was worked on before power supply was rebuilt, and I changed all 2sc1415 and 2sc726. Can't figure out what else to check.
