Yamaha M65 power consumption in class A?

[Edu1985]

How much does the M65 consume in auto class A?it gets pretty hot!so how much watts does it consume?
Also the 2/4/8 ohm.selector on the front panel i believe it has nothing to do with the actual impedance but only with the display and must be set according to the selcted speakers used,right?

Yes, it's only to calibrate the meter to the speakers rated impedance. It does not affect the actual impedance.

I live in Europe and here the electric bill gets higher and higher by the month but i still will use m65 as a heater.just curious about how many watts consumes in class A...i assume they are a lot from the 1150w written on the back

Class A amps have a power efficiency of %25, meaning %75 of the power gets dissipated, regardless of ac signal present or not. You can do some back of the envelope calculation using that …
