    Picked up an old amp today, looks to me to be from the sixties, but there are absolutely no markings on it that day any kind of brand. Face plate is gold. 3 knob. Speaker has a "pr12" designation so it must be a Jensen? Any help would be appreciated. [​IMG][​IMG][​IMG][​IMG][​IMG]

    Actually a Jensen would be PxxR for an alnico speaker, that's ceramic so the PR has nothing to do with Jensen likely. No other numbers on the speaker? The amp is a cut above many small amps-looks like a pair of EL84s and a pair of 12AX7s and a solid state rectifier-probably similar to the Kalamazoo amps of the 60s: 12w or so with a kind of lo-fi overdrive. And likely built for one of the department stores by Kay or Valco or Danelectro, then the logo fell off...

    I can make out the 220 code for Jensen on the speaker, followed by what looks like an 8 and then a 42. That would by logic make it a Jensen speaker made in the 42nd week of 1968.

    Doesn't help with amp ID, though.

    That seems right, and a biggish magnet, maybe a C12N or C12O?

    I dunno... maybe it's the knobs but for some reason this amp just seems to scream "New Jersey". ....A Sano perhaps? Or one of dozen other alternatives from the area...

    Ill get the rest of those numbers off the speaker tonight. It looks similar to a LOT of other vintage amps I have come across, but I can't find anything identical.

    Although it doesn't look exactly like this one I used to have, the overall feel and knobs are similar.

    This is either one of the last Valco amps (it has a 1968 serial number) or one of the amps that Strum N Drum assembled out of leftover Valco parts. I'm guessing it's the former because those look like 6973s, but it would have to be one of the lesser-known brands such as Penncrest. The speaker should have a "550" code somewhere on the rim.

    It's clearly a Dumble.

    Is that a copper chassis?

    It looks a lot like a late 60's Univox. Or even a Lafayette Amp.

    I was really hoping you were going to chime in, any time I have ever wondered about a vintage anything you have always had some good info!

    Valco....Supro, Airlne, National....etc.
    The Yahoo Magnatone-Valco Users Group is a good resource.

    Nmiller's right. That's totally Valco all the way, either non branded, missing the original logo, or assembled later.
