77 Selmer/Magnavox SVT 810 loaded with the stock Eminences of the day. Guessing at the power handling but I'd say maybe 400w tops. Certainly no more than that, and I wouldn't push it to see. Excellent buy, though. Great cab.

I saw some guy on You Tube, named esteban, re: dating ampeg cabinets.He said the cabs with the paper sticker on back plate, and paper tag on frnt.were only put on 77-79.I'd say thats 2 votes for a 1977 ampeg SVT810, so does that make it a vintage? And does anyone know what its worth? I'ts in pretty good cond. Except for the tolex. Thanx again for all your help.
