Hello, I was given six 700VA 20V(center tapped) transformers a while back, other than Beefy low voltage PSU's, what else could I use them for? They weigh a good 10 pounds each, and have a 120/240v primary, so I can run them back to back for a high voltage supply, but their size makes that somewhat cumbersome. I was considering using them as output transformers for a Push-pull tube output stage, assuming my calculatins are correct, wired for 120-0-120 primary, 10-0-10 secondary, that would give them an impedance ratio of 1152 ohms plate to plate? What would be some tubes to experiment with? Seven el84 in parallel on either side, fourteen per channel sounds like a worthy experiment, but I unfortunately don't have that many el84! Rewinding is out of the question. Any ideas?
