Default Faulty amplifier

I've now screwed them in correctly - the heatsink just needed re-seating
slightly. The amp has been on an hour and the module is stone cold.


** Not too unusual.


Indeed!

I only have a basic voltmeter, and a basic brain with which to operate
it.
I'd try swapping out the module if it wasn't too expensive - but any
more
than that would be well beyond me. Any basic diagnostic tips
appreciated.


**Look at the back and see if there are any RCA sockets that allow the
connection an external device between the pre amp and power amp - often
labelled "pre out" and "amp in".

If so - run a pair of RCA leads between them.

Many such amps have U shaped links fitted when new and owners toss them.


Yep - you're quite right! It has a 'Processor Loop'. I've since downloaded
a German copy of the manual - the diagram shows what look like bus bars
connecting the 'in' and 'out'. Nowhere to be seen. RCA leads connected and
it's sprung to life.

Thanks very much.



** Ah - another satisfied customer !!!!!

Visiting a taxidermist is not necessary.
