: I brought it home,cleaned it,and hooked it up.
: It sounded great for about a half hour,then it blew
: the main power fuse(5amp).I replaced the fuse twice

Oh Boy... BTW, this amp is a 202, or 100 Watts
per channel... It is fixable too, but I wonder
what the problem is. Try this one thing... Remove
the 2 "scamp" (Self Contained Amplifier Modules)
and see if it still blows a fuse. It *might* be
as simple as the bridge rectifier being shorted.
This does happen from time to time and is pretty
easy to replace after you get it un-soldered.
You can probably find one of those at Radio Shack.
I seem to remember that they're 200 Volts and 25 Amps. Also, look at the fuses (if they're not intentionally shorted out) and see if they are in tact. We shorted them out at one point to keep
the output from gong "DC" and hurting speakers and
making the power fuse itself blow instead when a channel went up in smoke. No burnt components is
a good sign. Another common problem with the 202
amps was that certain filter capacitors would go open because of bad revets on those solder
connectors...
Keep in touch...
