I guess this will be a question for waldo or anyone with some good pictures from 1972.
anyone know of a show when jerry was using the mc75 or dynaco mk iii. reason i'm asking is that these are class A power amps. also tube based. and are considered way above and beyond the non class A mcintosh power amps by the audiophile stereo crowd. I'd love to hear some shows where he was using these amps.
