commercial class AB amplifiers have efficiency rates 50-55 % to produce 100W of sound will consume 200 W of power At no load or no play conditions will consume 5-7 W for operating the amp and another 10 for biasing the amp ....
so an average commercial AB amp will consume 20-30W at very low power or stand by at the most

Ok thank's, that was not so much. Good!

fromLook back at post835.
I state the total power consumption of ~33W for the transformer + PSU + amplifier.
The output stage (1pr) alone consumes 0.47A * 62Vdc ~29W.
That means the Transformer + PSU + amplifier front end, consume ~4W
