Vintage 1976 Marshall JMP Super Bass 100w MKII Valve Amplifier Head *1970s*

This could be one of the first amplifiers with the 'newly updated' head shell box that Marshall introduced in 1976! It's an incredibly rare crossover period amplifier, with the old style chassis (toggle switches and bulgin plug), and the new style head box. It's a stunning piece of Marshall history! I found this one down South and had to grab it - it's a really killer sounding amplifier. All three transformers are original to the amplifier and work well. There is a quad mixture of great sounding EL34 valves for the power section, and a set of original Marshall labelled ECC83s in the preamp section. The capacitors date to 1975, and are in good working order. Has been serviced by one of my leading amp techs, and it's ready to go. It's one heck of an amplifier. Please have a close look at the high resolution photographs below, as these form part of our description. Grab a beauty!
