Jhndragoon, at this time, trading on this site is not permitted. I apologise for the inconvenience but the Wanted and For Sale Forum is under a bit of a redevelopment and there is a temporary non trade rule in place until this work is done.

You should be able to use the much more readily available 6SN7. Plug compatible.
What's the application?
Am I allowed to make recommendations as to where you can get them? Else there's my email address - I don't have any to sell BTW

They are the best solution to drive 2a3 op valves however I have seen 6sn7s as cathode followers used as well. the tube depot is noted however I'm sure some are left over here locally from the b&w TV days I will open up my email address in the tool box.
When Impedance is important!

OK I see what you are doing.
You can't drive them into grid current (and extract max power) with cap coupling so it's either a transformer or cathode followers.
I ran this up on LTSpice a couple of years back and I was pleasantly surprised at what you can get out of a pair of 6BQ5s driven this way. The characteristics of the triodes you use as emitter followers don't matter much, 12AU7s, 6CG7s etc all will work.

I think of a emmiter follower with an ac126 or af117n in circuit but maybe a couple of 6bq5s used as a triodes might work or I might try ecc99 or soviet eqv
