Ptss,
I would agree with Csontos, and suggest to seriously consider mods such as replacing and upgrading with better quality capacitors, internal wires , resistors, diodes and rectifiers , binding posts ,etc. Actually they do not cost so much ( compared to buying a new amp) but improvement in performance will be outstanding. I did it on my Cary Audio (AES SuperAmp AE-25 ) and thoroughly satisfied , even people at Cary were surprised at the good result.
Reg cooling : I had on the same amp custom installed a 3" cooling fan at the bottom to take air from underneath and throw into the body of amp. I had even a 2 speed regulator installed which make fan to run at higher speed ( more noise /dB ) while amp on stand bye , but run at half speed while amp in operate mode ( very low noise/dB ) . It works great !
