1974 Marshall JMP Super PA100, In GREAT Condition!

This a true piece of Marshall's history from the early/mid-70s. Whilst our JMP does hold some cosmetic damage to its tolex, the head's shell is still in great structural condition, and the amp itself still in great working condition & sounding superb! As is expected with an amp of its age there have been some repairs and replaced parts to keep it fully operational, Some of which to note are the internal smoothing caps have been replaced, Volume Pots 3 & 4 have been replaced as well as their subsequent High & Low input Jacks (all replaced components pictured). These repairs have been carried out by our in-house amp technician who has been working on vintage amplifiers (Marshalls especially) for years. 

As seen in the pictures above this is a point to point hand wired amplifier where many examples of these amplifiers even in the same year would have already switched to a circuit board construction, Although this is initially designed as a PA Amplifier, This JMP can and will still deliver the big, sweet Marshall sound we all know and love. This is ideal for the collectors and players among you.
