Excellent suggestions! thanks!
I did not know that about the zeners. I have used them before on other projects, and felt like they worked okay. Other amp builders turned me on to the zener trick.
I looked up the specs on the tubes, and this is where I am coming up with my voltages and currents.
As for the DC resistance on the transformer. you are correct, that number is wrong! I thought I had fixed that on PSUD! the data sheet on the PT shows it to be more like 277 ohms. I'll fix that.

I will give this all a try and get back to you with my results!
