Hi everyone, how's it going? First post here, hope you're all well. I'm in the market for a late 60s Marshall and have an opportunity to buy this amp. Hoping to get some insight from you knowledgeable folk about this 50W Marshall head from 1968. I have been told that: This is a super clean and mainly original JMP 50W small box plexi head from the early 1968 It has the original transformers It has the original Mullard EL34s and NOS 12ax7s Has a new Marshall logo fitted but also comes with the original Filter caps are newly replaced with F&Ts but it also comes with the original caps still intact It has retro fitted rubber feet (the original feet are also included) From 6 to 8 on the volume dial it starts to grind up From 8 to 12 it becomes a rock beast with an amazing natural breakup It has had 6 minor component changes, and the tech has apparently said: "We changed all the electrolytics, including the bias circuit. We added the .68 cap and 2.7k resistor to the bright channel cathode (as in most lead plexis) and changed slope resistor & treble cap in the tone stack from 250pF/56K to 500pF/33K to match most slightly later lead plexis. It fattens up the tone. The bits we changed were not original anyway." I've got lots of pics, which should help us determine how original and desirable the amp really is. I would like to find out what you think about this Marshall, what would be a fair price for it, and if there's anything questionable about it. All feedback is welcome! PS I'll attach more pics to this thread shortly.
