    Hi Guys,

    I recently picked up a 1936 cab and a JCM 900 for fairly cheap but I'm having a problem getting all the info that I need.

    I opened the back and have found it is a stamped backplate with 'YO5305' stamped on it.

    Can anyone give me a hand identifying year, original/reissue etc? It's a 50w if that helps at all. Attached is a picture of the amp.

    Thanks in advance,

    Dom

    Isn't there a white sticker with a upc code on it stuck on the back? If it's still there The first four numbers are the date of manufacture.

    Congratulations, you have a JCM900 MKIII. It is one of the more desirable model of the series. It is original, from the '90's, as there is no reissue of this amp. Enjoy.

    Some of MkIIIs will have a stamped serial rather than the barcode. Mine was a 91 and had it stamped / no barcode.

    If your amp has a Y stamped as the first letter of the serial, it'd make it a 1990 model, the first year they were made.

    The amp you have is a model 2500 MkIII. They didn’t reissue that amp. Marshall also used the 2100 (100 watt) and 2500 (50 watt) designations for the 900 SL-X (which replaced the 900 MkIII), so it can get confusing.
