I pulled V105 and CRT pin 2 went from -38V to +150V. Before I pulled it, the voltage on pin 7 was -85V. BTW, the funky voltage on CRT pin 11 was because of the position of the brightness control. It is 225V and correct when the pot is in the max voltage position.
That all sounds correct. Do you have another 12AU7 to try in circuit?
