"Noooooo! it does not draw 75A p-p all the time! The amp specs might say that it is capable of supplying 75A peak but the amp does not do that unless the load requires it. The 75A peak is just the max capability of the power supply transformer & capacitor bank to supply that much current.
it runs warmer to the touch 'cuz the bias is on high(er) side (to perhaps make it run longer in class-A before switching over to class-AB)."
Bombaywalla,
I am very aware of that fact but wanted to point out that because of the temperature difference of the (2) B&K amps I own. They both have very limited space above them in my rack so I felt a fan was only necessary for just the one amp that operated at a higher temperature. I don't know if it is better for the amp to use a fan to draw away excessive heat or not but I feel better about it due to the age of them(12+ years) and to protect my other components.
