I have that same amp model )))200((( on the front
it came with a blue jewel pilot light. I bought it in the 1970's
It works but very noisy. I have replaced a transistor in the preamp once before. I need a schematic and I am excited to dig in and fix my baby. Dom Franco

It sounds like it's a K200A-4 amp. There should be a XLR Jack on the lower right side looking at the back of the amp where the footswitch jack would plug in.
The early 200A series used a aluminum foil sticker on the upper left side on the back of the amp for model and serial number that could have been peeled off. Yours probably have round silver kitchen drawer knobs for the power cord wrap.
The K200B series would not have the By Ross under the power light. The )))200((( under the Kustom logo would be the B series and would have 1/4" footswitch jacks on models with effects.

I don't have any schematics for your amp. I've never seen a kustom K200A series labeled anything but BY ROSS INC. Does your K200A have two white circuit breakers, one on each side of the power switch? The circuit breaker models used a etched aluminum face plate rather than the black plexi face control panels that were used on the Frankies and the latter K200A series without the circuit breaker models. Glad to hear you have the footswitch. The footswitch is a must if you want to use any of the effects. The cool thing with the A4 amp is all effects were routed to the left channel.
