    late 60s Marshall JMP

    I'm having a look at a late 60s jmp 1987 model.

    Can someone help me with dating the amp or estimating its value?:

    - SN: S/11170
    - No bias pot: 68k bias resistor instead of the 47k + 25lin pot
    - I believe it's completely original only 1 resistor( v2 bias) + power tube socket have been replaced.

    thanks.

    is there a letter following the serial #?

      Amp has been sold in the meanwhile for 2200euros

      Apparently it was an early '68 plexi 50w.
      specs: no bias pot, B+ voltage was around 440dc
