Are the inputs vertical? Does it have a drake poewr transformer? EL34 tubes or 5881s? Stamp serial or sticker?

Weird, the earlier 800s had them stamped on, but had vertical inputs. The later ones had stickers with a barcode and horizontal ones.

The codes on the back of the pots will usually tell you what year they were made.

Out of interest, what year?

The S = '84

The S/A is a 50 watter. The 2203s only came in 100 watts. So what is it?

yeah have at it someone. thought I had it figured out but I didnt this is what I got:

- Front panel says jcm 800 Lead Series
- It has two horizontal inputs
- the Serial number is stamped on the back panel
- Serial number is: S/A S1800
- On the ratings section of the back panel is written 2203
- The back says MK2 Master Model 100w Lead


I dont know what to make of it. I am going over to the dudes house at some point to pull the chasis and see what is going on. Help if you can!!! cheers

It's a JCM800 100w 2203 from the year 1984. Don't pay much attention to the "S/A" or "SL/A" and so on. This was a transitional period for Marshall and it's very common for those pre-serial code letters not to match up. I also have a 2203 with S/A at the begining. S 18000 is a nice round serial number, easy to remember. Since Marshall doesn't reset to zero every year, you have the 18,000th JCM800 ever made.
