    Assuming the speaker impedance load is properly matched to eight ohms, the concept is sound. I once drew up plans for such a combo conversion and it is eminently feasible. The finished cabinet would've resembled a Super Reverb.

    Sounds heavy to me. I'd not want to lugging that around. Roadies would have something to say about it.

    Precisely the reason why I never built a prototype. But the engineering itself was sound. One of my clients seemed intrigued with the concept but ultimately had me build him a 2 x 10 conversion.

    2x10 does sound a bit more feasible, but I would love just to hear a 4x10 Deluxe

    Maybe a AA/AB763 Bandmaster head with a 4x10 cab would be better?

    I would think the cabinet and speakers alone would be worth close to $500. I can't tell for sure from the photos, but it looks like the speakers might be wired series/parallel, which would give an 8 ohm impedance if the speakers are 8 ohm (can't tell that either from the photos).

    That's pretty much a Super Reverb with no reverb

    Strangest looking speakers I've ever seen. The baskets look like Jensens, but the magnets? What's up with that?

    Yeah, I rarely use reverb since I'm going through FOH. I'll add tails for sustain but never reverb as it kills the stage mix.

    They are definitely Jensens. EIA Code 220. 1954 26th week? Or perhaps 1964? There would be alnico magnets under that strange cover held on by 3 screws. The 3 slots opposite each of the screws look like they would be for attaching the traditional bell cover

    They look like P10S or P10T, originally good for about ten watts apiece. Somewhat rare, usually found in hi-fi radio/phonograph consoles.

    So in that case, they might not have much value in a guitar amp. I guess it depends on how they sound. What do you estimate their age to be, given their appearance?

    I'd guess they'd be around 70 years old if the EIA codes are correct. No way of course to know if the coils/cones are original. i wouldn't write them off out of hand though -- they might sound marvelous. Many off these drivers were installed in up-scale consoles from National Radio, Philco, Magnavox, etc and were generally state of the art for their time.

    Aaaaand it's gone. The seller dropped it down by $20 (to $480) this morning. I did not buy it.

    I think you missed an opportunity Rob, but I have more money than sense.

    I tried to buy a Fender Bassman-10 from a guy in Thibodaux, Louisiana, but he is now "away" on Reverb. I offered to meet him halfway from Houston and pay his gas money and a seafood lunch, but no response.

    Something else will come around, I'm sure of it.
