Marshall JCM800 4010 combo from 1985 with a Classic Lead 80 speaker.
Mullard, Amperex and EI preamp tubes. Old pair of Tesla (not JJ) El34 for power tubes. I just bought a NOS pair of RFT El34s, can't wait to try them!
Don't think you will like the RFTs better than the Tesla's. We need an update when you tested them!
