Hi all,

I have a MK MX-2000 sub that no longer works.

Appears to power up but no audio.

I've verified the two internal fuses are fine as is the power transformer and DC rectifier which provided about 45 VDC to the amplifiers.

Hate to replace the whole Sub and would like to fix it.

I'm trying to locate a schematic or replacement amp.

Anyone familiar with these?

What would be common failures?

The unit takes both L and R inputs and since there is no audio I figure something common to both channels is faulty.

Any input appreciated!
