    Outside of calling in the serial number in on my 810E is there a way to get an idea of the manufacturing date for your cab? Mine is pretty old, but I don't know how old. Someone once told me he thought it was a '74 but I have no idea how accurate that statemeant might have been.

    I endorse & use Tech 21 pedals, Eminence loaded cabs, EMG pickups, Jim Dunlop picks & Ernie Ball Strings, BC Rich Basses.
    a '74 SVT 810 cab had a "square" back & no "towel bar". It also had a removable 4 wheel dolly for transport, not the 2 built in kickback type wheels like on the newer models. The original speakers would have been cts/eminence with square Alicno magnets. The grill cloth was silver, similar to the new "AV" model cabs. The input on mine is a single 1/4", but I believe stock was a 3 pin type.

    But if your cab states somewhere on it that it is an 810 "E", than its an "newer" cab.

    *...I thought the square mags were the Altec upgrade?

    They changed Serial #'s when SLM took over, E-mail Ampeg CS. They can tell you.
     
  5. There was NO "Altec upgrade" for the SVT. CTS was famous for having square magnets, and the Eminence models that replaced them were clones of them.

    The bluemuse info is accurate for the portions I can verify.

    I play it all. Whatever works for the gig
    Square mags should have been CTS.. Also it would have been a 4 connector XLR type if there is an XLR.. 2 pins for signal and 2 pinss to complete the circuit that would turn the amp into standby if the cable became unplugged by accident so as not to fry the amp.. Although I am not 100% on this but I beleive the 1974 ish only had a 1/4" jack.. the older 1969-1970s had the 4 pin XLR and the head would have had 6146 tubes instead of the 6550s.

    Thank you. I did not know that. Did other Ampeg bottoms like the 2 15' v4b bottoms have Altecs?
