Hi sorenj07,Thank you for your advice. I would try what you suggested this week end.
The bias of ac/pen is only 8V. In my first version, it is 12au7 instead of 12ax7.
I get the LPT circuit from the web site - http://tdsl.duncanamps.com/link.php?target=0925972A, it is the phase inverter from the specification of Philips in 1970. By the way, could you tell me what is different between connecting the grid of the 2nd half 12ax7 to ground and connection like this?
