It could have been. The theory seems pretty reasonable to me at the moment. Time will tell. I'll make up a new adapter card that runs both sections and add a pot to negatively bias the grid on one of them. I wonder if I need to maintain dc (for the tester)? Should act as a distortion control, I think.
The concept should apply to any tube, dual or not. I think a 6080 type would be a good candidate. Or even a 6sn7. I don't believe the tubes need to be of the same type, either. One could make a composite tube out of just about anything.
Not sure how patents or copyrights work if the idea had been published in a public forum. Probably too late already. Besides, maybe we're just ressurecting something that was done 80 years ago. On the plus side, it's not something I have ever heard about or seen used in the past ten years. If anything, it could make a nice article for audioXpress. If it works out nice on the VacuTrace, I might have to patch together an amplifier to prove it out with actual distortion measurements.
