My trusty Rotel amp has stopped working - a blown mains transformer
is suspected. There's no voltage on the transformer output.

I know its a long shot, but would anyone know the output
voltages or know where I could get a replacement transformer -
other than by taking it to a dealer?

Transformers are generally pretty reliable.
Is there any voltage on its input?
Does it have dual input windings for 120/240v?
If so, is the voltage selector switch working?
What are the resistances of the windings?
They should give an indication of whether it is working.

You could make a guess at the transformer spec from
the amp's power output and the voltage rating of the capacitors.

It would probably be cheaper to buy the RA930AX that's on ebay
at the moment than to buy a new transformer.
