Hi gang;
A customer brought in one of these old (orange)Rockford Power
300 mosfet amps that he found in a basement.
It all works but one channel had a blown fuse.
Along with The RFP 18N10 and 12P10 outputs, an MPSA06 driver and a 100 ohm resistor. I replaced all.
There's still distorted audio. Thought the LM833 opamp might be the trouble (had monster audio levels at the non invert input compared to the other channels) Replaced it with a MC1458.
Did not fix.
Looks like the problem is further up the input chain.
I thought I'd check out this forum for a diagram before I start drawing my own. (P.I.A.)
thnx

Email me and I'll send it to you. You can also get it from Rockford.

Check the 3.3vZ. They sometimes short and cause similar problems.

I will check the 3.3 zeners.
Wow! The thought didn't even enter my mind that it would still be available from Rockford.
