Thanks, I wanted to see voltages and such. I agree with other comments regarding testing, it's probably a bad tube.
This circuit differs from the Mullard in several ways. For one thing, the feedback loop from the output transformer to the EF86 has been eliminated. Do you know if anyone has measured THD or IM in this design? Most of my work is straight pentode. I'm curious how much reduction in distortion is accomplished with the screen taps alone.
