    I've acquired a vintage Jensen P12R. I don't currently have anything that it would be suited for, but I suppose I could build something that would benefit from having a vintage AlNiCo speaker as it's voice.

    The logical choice would be a 5E3, but that might be pushing an old 12 watt speaker to the point of trashing it. A 5F1 in a Tweed Deluxe size cabinet might be a better choice.

    The speaker came out of a 60-61 Harmony H305 that I serviced for a customer. After replacing the stock OT with an Allen/Heyboer TO20, a Weber Sig AlNiCo 12" replaced the P12R. The P12R did sound very nice in the Harmony, but with the new OT a speaker that could handle the increased low end was prudent.

    I didn't expect to wind up with the P12R, but the customer offered it to me as partial payment for the repair. So, now what to do with it?

    Already lost one Vintage Jensen, boxed up the other.
    To be honest they were both shot.

    This one still seems to be healthy, but I certainly don't want to do any damage to it.

    Did you also keep the stock OPT that was replaced, or was the replacement due to the original OPT failing?

    What do you think you are going to do to it that hasn't already been done over the last 50 years? Play it or sell it! Sacrilege to have it collecting dust...

    Maybe in a 1x12 cab with a PR type circuit if you're really worried? Though I'm sure a tweed deluxe wouldn't do anything to it either.

    That's what I have in my Clark Beaufort (5E3) - glorious.

    The "In The Box" Jensen is original to my '65 Ampeg Gemini I, so I'm preserving it.

    I'm running a Fane AXA12 that just blows the Jensen's doors off.

    Stock OT was replaced due to a wire that broke off inside the casing. I considered repairing it, but chose not to do so.

    I intend to use. I'm just looking for suggestions for circuits that will work with it without over stressing it. The Princeton Reverb is not a good suggestion, IMO. However, a tweed Princeton might work quite well. So, thanks for giving me that idea.

    Oh, I have no intention of leaving it in the box. I'll either build something for it, or sell it.

    I get the original speaker for an amp thing. And definitely a newer speaker will be more efficient.
    Actually I run the original C12R in one of my 62 Revererockets because it's inefficient. Had a G12H30 Anniversary in that one which I liked but it was too loud to crank up.

    They're a pretty farty speaker if you push them hard. Not such great clean tones.

    But they are GREAT for harp!

    I have one in my 50's Gibson GA20 amp.

    Want to sell it or trade it?

    Yeah, I totally agree, run low volume Jensens sound fine, but pushed hard they totally fall apart and lose all definition.

    I stoopidly blew the original CTS 15 watt ceramic in my '64 Reverberocket.
    Weber re-coned for $85.00, but running a Fane in there now too.

    Also lost the 10" Jensen in my '64 Supro Vibroverb 10" + 15"

    If preservation matters, box them up.

    I don't really need another amp, so maybe I should sell the P12R to someone who can use it.

    How about a powered satellite cabinet that plays 100% wet reverb ?

    I know some harp players who would love it. My brother Bruce, at Mission Amps in Denver, builds really great harmonica amps these days. Builds killer guitar amps too, but harp amps have become his specialty.

    I didn't realize you and Bruce were related. I used to own one of his 5E3's. Great amp!

    Something I think about but never get round to doing. Put a speaker like this in a cab and a newer one in your amp.
    That way at home you have something you can crank without getting so loud. But you still have a speaker that holds together better on gigs.

    I would sell it, it's worth some bucks. Check it out well though. Especially on the low E string from maybe A to C. I've had a bunch of vintage Jensen Alnicos and guessing about 50% of them have a bad spot where they buzz badly. Kinda bacon frying on a sustained note.

    Duly noted. It passes the low E/A to C buzz test. Great sounding speaker really.
