MKB	Re: Amp Build....Advice/Opinions Hello, Bob. I now have a Concert like yours, and maybe can help with a few of your questions. 1.)You may have to lower the voltage a little to run 6V6's, as the Concert has around 475V out of the rectifier. A bit hot for 6V6's, especially new ones. 3.)The output TX should work fine with either but you may have to switch output taps depending on the tube compliment. Maybe you could use four 6V6's to get approximately the same impedance as two 6L6's? 4.)I would guess that a 5AR4 or 5U4 should be able to handle these just fine. Also, your layout may be critical, as the eighties Concert is pretty cramped as it is- the power tubes are too close together IMHO. You shouldn't have too few preamp tube sockets however!;<)
