schematics needed desperately kustom kba 100

[bentstraight]

I have a KUSTOM KBA 100 Bass combo . I fried a circuit and know exactly what burned out but can not repair because the values are of course burned as well.I simply need the schematics of the boards to determine the exact replacement part so I can buy it and install.As always there are links for most every other kustom product but mine and i refuse paying a shop to do a few dollars repair to charge me shop rates.please help!!!!

Maybe it's on purpose.

Naughty naughty naughty shop guys, always trying to steal a penny here and there !!!

Now speaking seriously: please don't think that by just changing visibly burnt parts (and nothing else) you'll solve your problem; most dead electronic parts (specially semiconductors) don't show any visible signs, and must be troubleshooted, usually by mentally imagining what they *should* do and both by instrument measuring and functional tests determine whether they are doing their job properly or not.
Incidentally, *that's* what the shop guy charges, usually parts cost is small compared to that.
Anyway, good luck; and thank vintagekiki for his schematic attachment; I'm sure it must be practically the same as yours, at least close enough for servicing.
Hint: I highly suspect the TDA7294 itself, but unfortunately it might have taken other parts to the grave with it. Search this Forum for a "lamp bulb limiter" and build (and use) it, it's dirt cheap and will save a lot of frustration.

May I suggest - CONTACT Kustom directly and ask for the schematic.

Invoice: $0.99 for one hit with hammer, $9999.01 for knowing what to hit.
