HI clintrubber,
I'm going to start at +-18V for the rails and I'm going to see how far I can take it before something goes poof. Seriously though, I'm going to use Fabios PSU board, which is already built and allows me to adjust the rails. I hoping to find a point at which the opamp sounds it's best. Can I damage the output tranny by experimenting in this way? I don't mind making more melcors, but I do mind frying trannies. I did my best to match transistors and hopefully, I get good results. I won't have time to do any testing until later next week, but in the mean time, I'm hoping to put together a test jig that will hopefully help us all.
thanks,
mike
