I had one in a chassis and no matter what amp I built in it. It never sounded good. Always the bass sounded thin and in the end I had to trash it because of the mechanical hum. Perhaps it was worn out I don't know but the few windings it had where all pretty high dcr. I suspect that most the current in those trans are wired auto former off the mains.And most the core is for the heaters. As it turns out I have recently re coated the chassis for another go with a different tech trans to try again. This one has even less ht windings just 2 one center and one not but the dcr is still high. I still haven't made up my mind what to try but I think it will be a very low power amp in the hope I don't tax the trans to hard and if it is still crap I will throw it out and bolt a toroidal on top. Not worth the greif really.
