I need help identifying my jcm 800!

twistudriffer · 10-14-2008, 07:49 PM

ok I have a jcm 800 and I do not know what to make of it. All the evidence that is on it makes it a bit confusing. Please help me out. here's the info:

- Front panel says jcm 800 Lead Series
- one channel
- 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

The "S" ing the model # should put it at 84' but I didnt think they made horizontal inputs that year. Also, The S/A indicates that its a 50w but it obviously is not. Also shouldn't an 84' 2203 model say "super lead" and not just "lead" on the back panel?

I dont know what to make of it. Help if you can!!! cheers

Weird. I came up with an 84 50w as well but if yours is labeled 100w and has 4 power tubes then I'm stumped!

twistudriffer · 10-14-2008, 08:21 PM

yep sorry I forgot to add that yes it does have 4 power tubes

I know this ones a tuffy. Tomorrow I will post pics

I wonder, have you ever taken the chassis outta the wood cab and checked it out internally for any mods?

twistudriffer · 10-14-2008, 09:10 PM

it had mods done but it was brought back to stock. any theories?

kdickinson · 10-14-2008, 09:16 PM

My only thought would be a chassis change, or rear panel cover. Could it be that simple? Other than that I can't really offer any other solution.

twistudriffer · 10-14-2008, 09:20 PM

yeah I think I will pull em tonight just to get to the bottom of this. I'm not to experienced with dating marshalls any indications inside the amps chasis? If so and I'm guessing there is what are they? cheers

twistudriffer · 10-14-2008, 10:28 PM

ok so I pulled the chasis and it has a drake transformer with the serial: 1471-263/4 and a number on the side of the bell which is 684. I believe this indicates that its an 84'. The 3 digit number could be coincidence, but I read that in the 80's they changed their serial system and the number after the slash indicates its year.

Input on this is welcome. thanx all! cheers

Hi guys I'm new here as you can see. I'm from Belgium so my English isn't that much. Hope you don't mind...
Anywo: I happen to have the same problem as described above! I picked up a Jcm 800 head today and have the same identifying problems as mentioned here. I attached some pics (phone quality) so I hope this works.
I really would like to know what the hell I bought

Please help me out here guys, I really would appreciate it!

r3volution · 10-18-2009, 10:49 PM

Hey while we're on the subject I have a jcm that I have never seen before. Its a 212 jcm 800 combo. 50 watts. Can anybody tell me about it? I'd never heard of it till i bought it. Private message me if you have details. Thanks ahead!

Jesstaa · 10-19-2009, 06:14 AM

S/A NORMALLY means 50watts, but I've heard of a lot of S/A amps being 100watts.
