UPDATE: GUT SHOTS ADDED. Also, I believe it’s a 1968, not ‘69. I bought a 1969 Marshall model 1959 that’s seen a lot of action. Definitely not a collector’s piece, but I figured it’s probably the only way I’ll ever be able to own a 60s Marshall. It was $2K. I want to play the amp, not only stare at it. I pick it up tomorrow. A hole has been cut in the box for a fan, there’s spray paint on the back and sides, the bottom corners are fairly beat, and a master volume was installed in the rear. Most significantly, perhaps, is that the power transformer and choke have been replaced. I bought it without seeing the guts, so it could be a nightmare inside, although the retailer indicated that all the ‘signal components are original.’ It has a lot of character, if that’s worth anything. My hope is that it will sound very good and will be a great player’s amp. I may even partially restore it. The back panel has a serial number that seems to indicate it’s from 1969. I haven’t seen the pots. Hopefully I’m not being hoodwinked, but I can return it within 14 days if it's crap. My questions: If the power transformer doesn’t sound good for some reason, what do y’all recommend for a replacement? And how much does the PT define the Marshall sound? I’ve seen some who say it IS the sound. Thanks. I’ll post photos once I fetch it.
