I might try an outboard bias resistor. As for the output transformer, it's fine. I've even tried another transformer in there that closely matches p-p 45's.
The interstage transformer seems to be quite well matched. I get nice clean audio out of the secondary. In fact, I can drive a high impedence speaker directly from the interstage transformer at a good volume.
