These are some of  the amps I mentioned in another thread as I was quoted £380.00 per amp to service, replace the 24 capacitors,  redo the thermal paste reset bias etc .  I have sent one in to be done as a test & will collect early next week..

What i thought...also...kinda stupid design...Confused they could use one big transformer and that will be all....no need for the extra weight of two transformers...and also the extra wires etc etc...Confused if it was dual mono design with separate power supplyes i would understand,however 200w from 4 outputs per ch in 4r seems fine to me.

Well it would be an internals picture, IF I could get the panel off!  Some f**king genius seems to have designed a puzzle I have to solve first!
