Did you check the tubes on a good tube checker. You probably have a weak osc-mixer tube. Increasing the filament voltage, will increase the emission.
I was using a set of 1.2 V NiMH rechargeable D Cells, not the 2V Lead-Acid battery I had previously linked here and asked about.

Secondly I don't have a tube tester capable of testing the old style 4, 5, 6 and 7 pin tubes, so I can't check the tubes unfortunately.

I've tried to acquire one but everytime I find one they usually want over $100 for it, which I can't afford anything like that right now.
