Yes, I ran some tests to see where grid current starts. It looks like about 1.6V positive of (negative) filament terminal, with 1.2V on the filament. My leaky-grid AVC detector, for instance, is biased at +1.4V.
It doesn't hurt the valve, but I was just wondering in your circuit that running into grid current could cause AF distortion at the grid. Obviously, it is a non-issue!
