Thanks Sodacose, That explains a lot. And some other things i don't understand: 1. The Edcor WSM is 0.5W, does that mean it can only transfer 0.5W of power e.g given secondary tap drving 32ohm load then the transformer can only pass as much as sqrt(0.5/32) = 125ma, is that right? 2. What do you think about quiescent operating point affect the sound quality beside power dissipation and power output? i.e increase/decrease plate voltage, anode voltage, bias current.
