Well. Here's the thing.
If your oscillator is oscillating, but not strong enough, your grid voltage is not negative enough, and does not lower the current enough.
The SG shares into that total current and might draw ore than it should.
This could be as simple as a weak oscillator/mixer tube.
When measuring that voltage, try to make sure the oscillator is running (by maybe using another radio). If it is and the grid V is low, that might just be the reason, and them maybe installing a strong tube would cure it.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
