Ex perimentation...I`ve settled with 2-7025 `s each channel with one paralleled per channel-audio -press 03-01 plus 12ay7 and for low impedance 12au7a.I presume what you are thinking.TOO many tubes...My amplifier is also inspired from audio-press..sept 2001 article from a mr spencr. Needs A LOT of gain before you get there .6550 single-ended amp It really performs when the volts are there...
