quoted>>>The front-end produces a near-perfect 10 KHz square wave.into what load? try it through equal coupling caps and a grid resistor. Add to this a scope probe and it will probably look like a power valve grid, or at least enough to make some judgements.
Don't worry, not hung up on the square wave response, just a measurement ref. and test method. WIth loads other than the 'scope probe, response sucked on my test rig. B+ in the 420V range, plate V of the amplifier stage about a fourth...
Clearly we are doing something different, else our results should match more closely.
