EC8010. Thank you again, but i think that i need your help. Applying yor method in paper, results in more than 50 times the "normal" driving current. Is it in line with yor findings, or am i totally wrong? (If you like, choose 2 tubes, driver and output, and write down the results of your calculations).
Regards
George

James, Thank you for your information. I have to ask you though, how did you arrive at the conclusion i quoted above. Do you apply Kirchhoff analysis method, is it a rule of thumb, or is it your observation? I was really wondering myself about that too.
Regards
George
