I'm going to build a buffer stage to go between the output of a TVC into my PPKT88. Reason is to account for eq I need to apply for my room/speakers.
I've got a few ECC88's and ECC83's sitting around looking bored, can anyone advise on a suitable circuit utilising either of these?

Sorry Guys
I've just re-read my post and realised it isn't at all clear. 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.
