Some additional info i`ve found..

2203 head (1 channel, master volume) 1975-1981

2159 2x12 combo ("4 pronger", twin channel - combo version of 1959 head) 1977-1981

1968 head (8 inputs, 4 channels. "Super PA") 1966-1975

1959SLP head (4 inputs, 2 channels. Reissue of 60's plexi.) 1993-present

1959X head (4 inputs, 2 channels. First of the plexi reissues.) 1991-1993

1959S head (4 inputs, 2 channels. First Marshall reissue.) 1988

1959 head (4 inputs, 2 channels. "Super Lead". Tremolo model T1959 discontinued early 1970's.) 1966-1981


The 1959 model is refering to the schematics of the amp and you can find them all the way till early 80's and they are all Super Leads. They all have vertical inputs 2 channels/4inputs (JCM 800 1959 that's from 1981). Now what year is as real Plexi or not/metal panel bla bla bla you covered it right......

1959: 1966-1981 (the real ones boys and girls)
1959S: was in 1988 Marshall first reissue
1959X: from 1991-93 first reissue of the sixties plexi 1959
1959SLP: from 1993 Most accurate of sixties Plexi reissues




JTM 45 are not 1959 model nor Super Leads except for the 100watt because they used the JTM45's panel so there is some JTM45 (100watts) that are 1959's but that was in 1966 when Marshall made the switch to 100watt's amp to later made the 1959.

JTM45 are normally 45watts some 50watts and the very first ones, the MK1's or prototype apparently (1962-64) didn't even have a model number then it became the 1987 MKII (the lead version, high treble and normal channels....1965-66), there were the Bass version the 1986 JTM45 from 1965-66, they even had the T1987 for tremolo version same years

Now the JTM45 reissue is the "JTM 45" and started in 1989, it's the reissue of the old JTM45 1987model of 1965-66

And they had PA and organ JTM 45's also but that is an other story
