ml8, could you tell what voltage and anode load you used the 6s45p without bias? What about grid stopper, etc.?

Kinda of 100-110 V on a plate. I didn't measure current cause by looking at curves i was confident that i'm not overpowering tube (working point for zero bias and 100 V on a plate is way below maximum plate dissipation curve).
I'm not using grid stoppers cause they have negative impact on sound and there was no problems with parasitic oscillations.
Grid leak resistor value was 470K.
