Well, I measured the cathode voltage and it's 3V, so the grid voltage referenced to the cathode is -3V. Given that and the plate curves for the 2C22 I'm thinking 175 plate volts with -3V on the grid looks just about right - gives 16mA plate current and 2.8W plate dissipation, where the 2C22 max is 3.3W.
Puts me smack in the middle of the linear region for the 2C22 as well. 100V is in a non-linear region, so I'm surprised it sounds as good as it does; can't wait to hear it in the linear region.
Thanks for all your help with this!!! I think I've got it now...
