Late last night I was contacted about doing a local trade swapping my 1974 Marshall JMP50 for his Blonde Bassman. He wasn't sure exactly what year it was but said it had recently been fully checked out by a reputable local tech.
A few hours ago he brought it over so he could check out my Marshall and I could check his amp out through my cab. It sounded amazing and from what I can tell it's pretty much original aside from a few necessary cap changes and some holes drilled in the back of the chassis. Whatever mods were done using the holes, if any, have been reversed and the blue molded caps are still there.
What's interesting is that the tube chart is mounted on the bottom of the cab and is the old style without the tube drawings and just has letters like you see mostly on '61s. The chart is for a tube rectified 6G6-A and is stamped February of '61, but the output tranny and choke are from the 36th and 41st week of '62. The choke is from late '61. It definitely left the factory as a solid state rectified 6G6-B, so either they used up an old tube chart, used up an old head cab, or it was put in a different cab at some point in it's life.
