Tonight I will input a test pattern and re-do the voltage measurements. Is the low voltage on pin 2 of the 6sn7 a problem? Should I reduce the value of the 560k plate resistor to increase the voltage? Would it be helpful if I sent the schematic? If so, can you send me a personal message with your email address? Thanks!
