Help guys,
I watched, watched ... at the forum, but I could not find it.
Once upon a time (25 years ago), I had a schematic for MC tube preamplifier with MOSFET in an anode on 24V (I mean, I'm not sure) and a large block at the exit.
Does anyone have that schematic?
Please ...
P.S. If someone did it, how does that sound?

Me and friend of mine used it about 1989 year 
I found scheme in a magazine, don't remember which one.
With ECC88 and voltage source in anode. 24 V power supply.
We change voltage to current source with bipolar transistor for better sound.
And, unfortunately the scheme and device was lost years ago ...
