1976 JMP Master volume model MKII

Post by tsl602000 »

I scored this sorry piece of Marshall for $150. I'm planning to restore it. It's one of the first MV models Marshall made.
The PT is missing, it needs new caps and a cabinet.....

It's an early 2203. I know exactly what it is. I was just posting what I got...

Okay yes, 2203. I missed the two extra filter caps in the first photo. It appears f that there was no way to jumper the inputs ion the early 220X series amplifiers - sacrificed for a Master Vol pot. Later schematics show that the inputs were ganged in series (ala JCM800). Does that sound right?

Thanks - and good find.

This amp still has the original Daly 50/50 can caps. Do you guys think I should replace those?

Thanks

Hee Nederlander! :D

I would replace those old caps as one of the first things. Don't forget those bias caps when you are in there... Cool amp!

Have fun!

Yeah, as Dutch as can be..:-p 8)
I scored an original NOS faceplate on Ebay. The original one is missing. How lucky can you be?
Anyway, the reason I asked is becuz you see all these seventies Marshalls with these original Daly caps still going strong.

Coen,

My 1959 superlead D series (Marked Dharma on the front BTW!) sounded a lot better with the old caps replaced. They were the dark blue caps BTW.

I have the same amp and it still has the GE 6550's and the original filter caps and it sounds killer!
