Durn it... -> CCS?

Thanks Kurt,
That was another thing I was wondering about, although I forgot to stick that in my first post. So with my output, I'd need about a 7.5K resistor to stay above a 2.5K total load on the 2A3, at which point things would get bad wrt voltage dropped and power dissipated.

However, I've been doing some more reading and found Gary P's post on using a pentode CCS on the output tube. I have the parts to try that... The only thing that I'm not sure of is how much voltage I need to have across the CCS. Say I want my the plate-cathode voltage to swing 100V each way from the static condition voltage. Do I just need 100V plus some reserve across the CCS to cover when the tube needs a higher voltage than static conditions?

Thanks,
John
