Thats right, no center tap.... Back to the drawing board :)
Too bad you abandoned that transformer. You should have rented a skid loader or farm tractor with a loader. My 1959 farm tractor, which is small compared to modern ones, lifts round bales of hay all the time. They weight anywhere from 650 lbs to 1800 lbs. It struggles on those
1800 lb ones, but a larger tractor could easily handle a ton or more. (I dont buy or make bales larger than 1500 lbs).I thought that same thing, but they apparently can and did handle that abuse, The Greatful Dead,"Wall of Sound". Was entirely run from Mcintosh MC3500, Tube amps, and the MC2300 solid state amps, having a total of around 28,000 watts. Not the intended use, but they held up....
Im not real familiar with transmitters, but I know that tube is used in Ham transmitters and is similar to a 6L6 (or am I thinking 6LQ6?).
