At lease a SET tube amp draws constant current which is modulated through the output transformer. The current draw does not change - increase - when louder passages in the music play. Therefore, you need not have the high current carrying capacity of a push-pull or class B requires. I agree with the other answers telling you there is no need to worry about it.
Class-A Amplification and 15 Amp Outlet
Pardon my electrical theory ignorance, but I have always been intrigued by the beauty of Class - A sound, as such, I am actively exploring a purchase. My question is based upon the power draw (even at idle) and the ability of a 15 Amp wall outlet to provide such without tripping. I have looked at the "big boys" from Pass XA160’s, Gryphons Essence Stereo & Antileon EVO to name a few. I do not have the option of installing a dedicated circuit in my unit. So, would I be ok if the electronics (including a DAC/preamp) were on the same circuit?
Thanks!!
