Amplifiers dating vox amps
If the speakers in your Marshall cabinet or combo are original, they can provide another piece of evidence when determining the date of manufacture.
As many cabinets did not have official serial numbers before 1992, this can be especially helpful in dating earlier specimens.
The first Marshall amps were made in England starting in 1962.
Production has continued there uninterrupted through today, though some lower-priced models are now made in China, India or Korea, depending on the series.
From January 1984 to September 1992, the three-part coding was used by Marshall but the date code letter was moved from the end to the middle. This would indicate a 100W Super Lead (SL/A) built in 1989 (X), production number 10059.Often these specimens produced between October 1962 and December 1964 had an offset chassis.Look for original black levant covering, a gray grille and the old block-style Marshall logo.These current serial numbers are arranged in a letter-ten digits-letter format (A-xxxx-xx-xxxx-A).These are still found on stickers with a bar code on the back of the amp.
