Saw this on TDPRI.

Gruhn ‘63 Prototype JTM45

Premier Guitar did a demo of it:



It sounds great. But come on, $200k? I know it's a historical piece but still...

No gutshots?

No gutshots?

You can see an image of it somewhere at the end. All electrolytics and a few coupling caps have been replace at a quick glance. So not 100% original

Thanks for sharing this with us, very cool indeed.

 

[BygoneTones]

Yeah right, whatever.

A Ceriatone clone of it with a Mercury OT for $1700 would slide right on thru a blind A/B. Just sayin'....
But it is a cool piece of history to those of us left that still care about that sort of thing.

Cool amp but not 200K $ cool

According to Ken underwood, Marshall never made any prototypes, they couldn't afford to. There certainly weren't 6 of them. Not having watched video, I call foul.
This may well be a very early JTM45 granted, and a cool find but that part I do not buy.

 

[Jethro Rocker]

Cool amp tho. Sounds like it was one of the first 25 or so, likely.

@Ken Underwood please.

That makes perfect sense to me. Especially given their reputation for doing anything and everything to get products out the door and sold. So maybe they are very early models. Or maybe they are no different than a counterfeit Ferrari. Believe it or not, those actually exist.

Early Vox knobs, that’s a first. Can’t even be bothered to watch the video.

Here are the screenshots:



I don't know much about this era, but a couple of things stand out immediately:
- The PI layout looks wrong for 7 turret-wide board. Likely cut down from an 8 turret board (as MG were known to do).
- The yellow/blue Dubilier caps are anachronistic (should be grey RS PIO).

Now why would the mains transformer have the voltage selector on top? Doesn’t this era of RS mains transformers (if that is one) have all the voltage taps on the bottom? That style end bell is also painted in hammer gray when it would normally be just a plated or raw metal end bell. I am glad I am not in the market for one of these.
