buffer stage ECC88 or ECC83?

Sorry Guys
I've just re-read my post and realised it isn't at all clear. :clown: By needing to compensate for equalistaion I will need some gain, around 9dB to be sure, and as far as I know cathode followers have a gain of a little less than 1 so these are no good.

Any suggestions for a stage with a small amount of gain preferably but not exclusively using ECC83's or 88's

A couple of ideas. There are quite a few circuits around using the 12B4, a NICE tube with low mu. Build with the ECC99 or 5687 and use a 3:1 step down trafo at the O/P.

BTW, the trafo idea works with the 6922, but you still get 20+ dB. of gain. Perhaps, that's too much.
