WTB 1977 JMP 2204 or 2104

[Fish17]

I'm looking for a 1977 JMP 2204 or 2104 combo.

There are few I found on craigslist and reverb but only most are newer than 1977.

I'm based in Pittsburgh but I'm willing to drive or cover shipping costs.

Why a '77 if I may ask? They made them until 1981

2 reasons, the earlier ones had the lower voltage power transformer and mustard film caps.

Do you have one for sale?

I have a '78 2204 with a B+ of around 360v, but I am in the UK. '77s with mustards are a bit hit and miss to find. My first ever 2204 was a '77 with mustards and that was a lucky find. I would say this, but I think the B+ is the most significant thing about these amps tone wise. The subtlety of a mustard cap is a bit lost with an amp like this IMO.

My brother has a 79 2204 for sale. I believe it has mustards.

As Andy said hit or miss for 77 with mustards. they started using the green caps (2 kinds) in 76 and 77, so don't assume.

Unlikely a 79 will have mustards, more likely it would have the brown ones.
