ECC82's can sound good in a mu follower topology, I can post a schematic if you're interested.
Yes I am interested, and till now I do not understand what advantage your talking about.
And what is the mu follower topology concerning?

What if I have a LP that was recorded and mastered on SS equipment, should I not bother listening to it on my tube amplifier?

Lets leave aside the silly topic about the source. I don't like this tube but I have some nice NOS 12AU7's so I built this preamp. It sounds quite good. Don't know the reasons why this tubet sounds good in mu follower and awful in a simple grounded cathode configuration (so don't ask me).

BTW, schematic was recommended by Bruce Rozentblitz. Probably misspelled.

EDIT - Mine has a different power supply.

None according to you. Do some reading because I don' feel the need to explain the circuit.

C8 looks like bootstrapping the grid of the upper triode.
