I have an use a 1961 MC240 that was significantly modified by Mike Samra. IMO some of the best output transformers ever made.. IF you want to hear what your gear is capable of, modern power supply bridge / caps / regulation, pristine nos tubes, great coupling and interstage caps and importantly isolation… even the dense 50# MC240 greatly benefits, i use HRS.
Best Vintage tube amp / preamp manufacturer
From the 60’s and 70’s. Macintosh obviously comes to mind. And which models of the brands. There aren’t that many but I am interested to know your thoughts.
I have a bit of a Mac and Fisher collection going on.
