Should? That is one operating point out of countless others: the 120v, 100k loadline at a -1V quiescent point is perfectly valid. Also note that 220K with a 120V supply will have little output headroom running near 1mA static. The C12 operating point is a good compromise between noise, input single swing, output headroom, and output impedance.For like a 120B+, self Bias should have a 220K plate resistor& 3.8K for cathode for around -4 grid voltage for class A.
-1 at the grid would be for more like a 12AX7 or a 12AU7 on self bias.
+1 on PSU PCB’s …Any chance that these boards will be avalible again?
