those were made when ZED owned the name(or company).those days of great hifonics amps are long gone.......
why would you need it?
a simple post here could get your questions answered.
if you`ve lost the plugs check ebay.
If it turns on THEN draws a bunch of current, the outputs are shot.
If it draws a bunch of current immediately upon connecting power (but not the remote wire), it's the PS transistors. Usually IRFZ34 or BUZ11's in these oldies.
