Marshall JMP 50 Watt Amp Head from 1978. Sticker shows tested 7/1/78

Drake Transformer - 6550 Sovtek Tubes - 12AX7 Tubes

Serviced in 2018, Tubes all work, may need to be replaced in the near future, Sounds Great Now!

Great condition for the age, works perfect, (see pictures for condition)

I have had zero issues with the amp but did have it gone through and tubes biased and replaced at local amp shop. I haven't used it for about a year, fired it up and tested, Sounds strong! I always ran it through a 16 Ohm Marshall Cab.
