Kustom 250

[lowell]

Need schem. When fuzz is on it loses volume after the amp is on for a bit.

[Enzo]

Come on Lowell, you know the drill. What are the board numbers?

Just from your description, I;d be thinking a small value electrolytic is dried up in the signal path.

[lowell]

Yes exactly my thoughts, but a schem would help a lot. Got one?

[Enzo]

Without a board number, I can;t look up the schematic. Look on the circuit boards for numbers like PC5033. I have a hundred schematics, I can;t post them all.

[lowell]

oops my bad... So I can only really see a # on one of the 4 boards. The board with the top channel control knobs attached says PC5067. Does that help?

[lowell]

not sure if it helps but serial number is 95213 and model is K250-4.

[Enzo]

Every board should have a PC number on it somewhere on the solder side.

Here is the PC5067

[lowell]

Enzo thanks.. so it's PC5069 I'm looking for if ya got that one too..

[Enzo]

I'll look.

[lowell]

Hey Enzo, got that schem? thanks in advance.

[Enzo]

Here

[lowell]

thank you thank you... kustom says they don't have the paperwork on the old stuff.

[Enzo]

Kustom doesn;t, but AES might. They have a huge supply of old Kistom boards for sale, and some original parts as well, might even have this one. I have not checked, since my collection is pretty good, but they may have documentation.

In fact, that is something I should look into.
