I just picked up several Identical power trannies from tube tv's for nothing. 3 of them are the same. 5v winding 6.3v winding and a high power 322vac winding. Problem is that the 322v winding has no center tap. I was wondering if anyone has experience dealing with this problem. The trannies are RCA branded, and they all ohm out the same. Could I use the 320 from one and the 320 from another and use one rectifier for 2 trannies? Can I use the winding without a center tap? Does not seem like a complete circuit... I'm hoping to make some high power tube monoblock amps but I am just getting started, and I figure the first step is to design a heavy duty power supply. any advice would be appreciated.
