Kustom X MPA Mono Power Amp

Postby Jjammy5152 » 26 Jun 2018, 21:00

Wanna know if anyone might be able to get or find a schematic for a Kustom X MPA MONOURAL 135 @ 8 ohms Power Amp
which was made in the early 70’s....
When I hook up this amp through a p.a. System I get sound for about 5 minutes and then it starts to have an unbearable LOUD hiss which cannot be controlled by the volume at all...
I then turn it off....
Any help would be appreciated.....
Jim

Hi and welcome.
Did you try contacting Kustom and asking for a service schematic? I see they have a customer service and parts dept contact email on their website (assuming we're talking about the same company).

I did contact them and also through their website of Vintage Kustom Amps, I was able to to talk to Don who gave me the information about the board number which I found.... Found a schematic for this but some things just don’t look right even though the later models had an e.q. Section added on..... :roll:
