Question about Audio Players & Recorders
I have a pioneer m-770 amplifier and as i was playing music it turned off now wont turn on, i opened it and check to see what was the problem and one of the fuses was blown. i replaced it wth 250v fuse from radio schack but when i turned it on the fuse blew and then then i tried swicthing to a 125 v that belonged to the amp but the transistor blew also, i know for sure i need to replace that transistor but what about the fuse and why wont it turn on?
You probably have a short in the circuit some where. you need to replace the transistor and look at all the solder joints to make sure there not damaged or cracked. i have the same amplifier and i replaced the fuse several times and it blew every time up until the last time when the 4 of the power output transistors blew. what ever you do do not try and power it on till you do all the things i told you or you will have sparks and fire. my mistake cost me my amplifier. but might help you get yours repaired
