I have reread your post on this thread...

and I don't see any use for a CCS.

It seems to me that you want to build two SE amps as shown (with the exception of fixed bias on the output tubes) and drive one push pull output transformer with them.

There's nothing wrong with that.

(Sorry, I was originally thinking something very different)

"So, a concern has been to equalize the gain of each single ended stage."

If you make one of the 390 ohm cathode resistors adjustable then you could manually set the AC balance.

That's the best idea I can come up with.
