Schematics and Layouts / Re: Boss Katana50 MK1
October 19, 2022, 07:55:21 AM
I bought the amp second hand, No output or function lights working.

I believe the main power amp TDA7293V had been damaged by a power spike and found to be fried.

I replaced the chip and it checked all components upstream from the chip. All were found to within spec, but the the amp still is dead.

Any idea's would be apricated.

Thanks

Hi,
Does anyone know if the existence of a schematic for a  Boss Kantana 50 is available ?

It seems only to exist in people heads like the fabled unicorn.


Regards.
