Grab a copy of Dunans Amp Tools TDSL Personal addition. Its Free.

If you do that, you will discover that the PCC88 is a 6DJ8 with a 7 Volt filiment.

There are many 6DJ8 (also called 6922 ) Schematics to choose from.

Well not quite... but still a good tube and can be used in similar circuits.

The russian equivalent is 6H23pi (aka 6N23P) which are also labeled 6922 at the factory.

You can find some circuits at this sites.

Or maybe something along the lines of Morgan Jones headphone amplifier (probably pretty good as a pre-amp to)

IMO, the biggest problem with the 6922, et al in line stage service is its "high" mu of 33. A simple common cathode block has too much gain.

What sort of a source is the line stage going to be used with? If it's a CDP, no gain at all is needed and a tricked out cathode follower buffering the level control will be just fine.
