Is your 0D3 glowing inside (the tube not outdoors)??? Is the 10K resistor 10K?? In terms of amplitude the 6SL7 is being used as cathode follower to give a low impedance output. Wouldn't expect to see a lot of gain there. Amplitude is probably going to be about the same. The other half of the 6SN7 is the audio oscillator which generates the 400cy tone for the modulation.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
