Yup; he was never real open about how he did some of the "successful" schtuff he was able to accomplish.
I¡¯ve probably converted?half as many as Carl did and 18-20 watts gave you?about as much output as you¡¯d dare.
So, Lou: are you saying that you believe Carl converted this "SB-206" to full grid-driven instead of grounded grid?? If so, that certainly does help explain why tuning seems so touchy; I wouldn't have believed that if you hadn't mentioned it.
Tell us, Lou... did you modify yours to grid-driven, or were yours grounded grid??
