Thanks.

I presume the 2x knobs on the front are volume controls for each channel.

The inputs on the rear do not look like RCA's?

It doesn't look like a PA amp.

Those Penbro transformers comes from Telekom industrial battery chargers.Some big enough to step into ! Def not PA, those output trannies are too expensive for that.

I have a 120 watt Dan Jakobs Anihillator and this has 2 power transistors per channel.   The 250 watt version uses 4.  But of course this will give you 500 watts total.

There are guys on the forum who offer an upgrade to this board which improves the sound trremendously
Even duct tape can’t fix stupid… but it can muffle the sound
