Hi all, Longtime browser, first-time poster here at Marshall Forum (and excited to say that I finally am a member)! I am currently considering purhasing a 1969 Marshall JMP 50. The seller wants $1800. I was wondering if anyone on this site could help me identify if everything on the chassis appears to be original/checks out. To my untrained eye, it looks as though the power transformer (second photo) has been replaced judging by the phillips head screws used and the fact that it looks much shinier and years younger than the other components. Also, on the factory inspection slip, it looks like someone left a note in the "Assembly" line about the transformers. I can't decipher what they wrote, but maybe it has something to do with the replaced transformer??? Does anyone think the same? Apologies about the limited scope of the pictures. Unfortunately, I was unable to get any photos of the guts. I will see if I can get a hold of those if I decide to more seriously pursue this amp. Thanks in advance!
