Today¡¯s measurements:
1- Both 6EW6 measure good and strong.
2- Pin 6: +3V
3- Pin 7: +1.6V
4- Pin 8: -4.7V instead of -145V
5- Between Pin 2 and R55: +3V instead of -151V
Stephen, I suppose you misread pin 3 as pin 8 (cathode, "A") in the schematic. That -145 V is measured with Amplitude at maximum. Did you perhaps set Amplitude here to minimum? (But I still would expect pins 6 and 7 to be slightly negative then, not positive).
