    I’m no expert but it looks like a 100 watt Super lead, that’s what they say on the Gear Page, and that’s what it says on the amp. 4 power tubes, no master volume. Probably a 1959 model JMP? Late 70’s, early 80’s?

    Yep, dates I can see show 78/79/80. It's a 1959 Super Lead with typical "JMP" trade dress.

    And looks to have been a rental/studio amp.

    Also not an expert- but this is the obvious stuff. I'm sure the experts can look at the pcb and figure out more details.

    Not later than 1979. In late 1979 the serial number block was added to the front panel to the left of the power switch.
    It's a 1959.
