An old Mosfet Amp from the 1980's, currently in need of some repairs, built for Bass Charrington Pubs - Toby Sound amp TSR-450S, 'larger brother' of the TSR-150X earlier in this thread.
One Channel tested into 8ohms is 200watts output and the design rating is 2x 225watts into 4ohms.
View from the front before cleaning and repairs - a sort of 'before' pic:

what's wrong with the Knobs and Caps?
They're contemporary to the Amplifier - seems some people just don't understand keeping things as near as possible to original!

Maybe Contemporary but there ugly, they look like they don't belong on it and make it look cheap, they don't match the Black with Red front panel, They'd look fine on a cheap old mixer desk with silver and black front panel. I'm not saying that there not original but if they are the designer was colour blind.

I like the long centrifugal blower on that amp, never seen that before. Bet it's a lot quieter than a couple of 80mm axial fans screaming away.

Large format cross-flow fan is a clever idea, super low noise and great volumetric air flow.

Unfortunately smaller versions than 2U do not really provide enough pressure...
