im thinking of building a high power amp (>600W) for my bass player to use. Im thinking of using 4 or 6 813 beam tetrodes. i am planning on winding some toroids for the PT and OT. i found this site: http://www.alphacore.com/ocore.htm
the QA-1000 has a VA rating of 1200 to 2400. will this be enough to get a wide frequency response from the OT? do I need to go that big on the PT?
also, ive heard that toroidal OT's need to be air gapped. The amp is going to be push pull, so do i still need the air gap? if i do, how wide does it need to be?
thanks for any help, Kalen
