Ok. 230V wiring performed. Heaters up to 5.9V across the heaters, but all values went up. The PT is rated for 300-0-300 HT.JMPGuitars wrote: ↑Tue 03/24/20 2:38 pmInteresting. That could be the culprit. Let us know what happens.
Now the B+ is way up.
What do you suggest? Start tweaking the cathode bias resistor or wire the PT back to 240V ? Or put a resistor between the EZ81 and the first filter cap?
Second line of measurements is 230V , first line is 240V
