if I  could sell my Mark V this would have been a keeper for sure.

Hi Si. Is it all original no mods etc. iv got someone picking my blackstar up on Saturday. As long as that goes through ok I'll have the funds. If you still have it by the weekend and mine goes through I'll have it

There was a disagreement over the power and Ohm selectors on the back with someone, but i think it's all original.. I've not had the chassis out to check the internals, but when I got it from sted here he said it was original.

HHwarner

Don't suppose you could do a gut shot could you. Be careful of the arse end of the caps though

I'll try and get one over the next few days but quite busy at the moment.

HHwarner

No problem dude cheers

Here you go... light isn't great as it's getting dark here. I'm no expert, but all looks Ok to me, no obvious mods or anything new.

Obviously as you can see from the other pictures, it's not New condition , plenty of scrapes, scratches, tolex missing (there is a large bit of tole smiting from the bottom which I didn't know about until jet now, but you never see that anyway), knocks and dings, and I can't voice for how old the valves are... BUT to my ears it sounds fantastic..

Where does that white wire go to, the one with the cable tie on. Looks like the middle preamp socket base. Not sure what that is maybe ICBM might have an idea?

Si_

I've asked the question in the Amps forum, but looks simple to de-solder and remove. Curious what it does myself.. That seems to be the only anomaly, I've sent pics to my usual amp tech and he said it all looks un-modified and original spec. 

Si_

Also asked the question on the Marshall forums and seems to just be something that was done at one of it's services, nothing unusual:

It is not really a modification. Someone opted for a shielded wire to the grid on that preamp tube and connected at the load resistor on the board.

If you still have it by the weekend and the sale of my blacky goes through I'll take it. I'll let you know at the weekend. Cheers Scott

these beasts of amps...100w none master volume...how loud before they start to break up ? I'm guessing floor shaking and windows shattering loud ? So....if so does this mean its a clean amp in the real world use it will see and needs pedals to get any dirt ?

This is a JMP 2203, so it has a master volume, no need to crack it up to stupid volumes to get a great tone. 

Here's a few samples of what you can get out of it.
