Pioneer SA-6500II Repair
I've got this amplifier in not working condition. It was supposed to be scrapped but I would like to bring it to live. I've changed all capacitors, put deoxide to pot meters, cleaned etc. I've also changed power transistors. I installed Motorolla MJE15032 and MJE15033 accordingly. But when I turn the unit on, after around 1 min. fuses in -+34V rail were busted. I've checked the transistors and found that one pair is completly gone. There is shortcut between emitter, base and collector....Can you give me some help/advice guys.....as I don't have so much expirience..
Thanks in advance
