How did it turn out? I have the v55hd infinium.
I’ve been looking into changing v1 to a 5751 or 12at7 as suggested above.

Did you change any other tubes from 12ax7 and are you using 6L6 or find a alternative?
I'd give two configurations a try: 2 12AY7 into a balanced 12AX7 PI and keep the 6L6s OR 3 x 12AX7 into 5881s (rebiased, of course)  ... if it were a head instead of combo I'd probably opt for the long plate 12AX7s and the 5881s

Mine is just a head, V55HD.
The Infinium is supposed to automatically bias the tubes, would I need to do any mods to make the 5881 tubes to work in place of the 6L6?
As far as I know only the power tubes are biased automatically, the only two that have an LED on the back of the amp.
