    I have a beat up JCM800 1960B 4x12 straight cab and I decided to check out the speakers in the cab. It is loaded with Celestion G12-65 15 ohm speakers.
    I have a few questions about them:
    Are the speakers valuable?
    They are all stamped T3054
    3 of them are stamped HP19
    1 of them is stamped JP21
    Which series of numbers is used to date the speakers? What day/month/year were they made? etc etc etc
    Any info would be much appreciated.
    Thanks

    HP19 = Aug 19, 1981
    JP21 = Sep 21, 1981 (Assuming they skip the "I" for months as well.)

    The first letter is the month, and I think they skip "I."
    The second letter is the year, from '68-'91, skipping the "I" and the "O."

    If you're at all interested in Marshall, Michael Doye's The History Of Marshall is a great book to have.

    I'll bump this because I have the same cab and same speakers. Bought it used a few years ago for $200. Cabinet was pretty battered but all the speakers work.

    It is currently sitting underneath a Marshall DSL-50 head and is probably one of the main reasons that I am of the few people on this forum that LOVES my DSL!

    the crucial thing with these speakers is the number on the back of the cone, either 1777 or 444. the 1777 are lead cone and sound very good with guitar, the 444 are bass cone and sound much less so. In the cab you describe, they should be 1777's.

    In good condition they had been going for ~$125 ea. Although recently a couple have gone as low as $80 ea.

    Now I gotta go dig up those speakers I bought in '81 and check the codes.
