I have a Sirius (Gamut) D100 power amp which is a dual mono single mosfet model
Two nights ago whilst warming the system up prior to listening all power went off and by the time I got a torch the room was filling with acrid smoke.
I took the lid off the amp and found one of the transformers insulation was burnt and discoloured and stank!!!
The power caps appear to be unmarked.
Some pics below










Some of these are with flash and some normal.
What are members opinion when something like this happens?
With a transformer gone would repair be a cost effective option,presumably with dual mono both transformers would need to be replaced??
Any engineers opinion welcome

BTW how do I test my speakers to see if there is any damage there? There was nothing playing and my RDC tripped everything out PDQ
HELP
