    Awesome info guys, thanks. Where would the serial number be on this amp? I haven't seen one so far.

    Would you all do anything about the 2 prong plug?

    and they're only fifteen bucks each. :rolleyes:

    Let's use Atoms under the doghouse while we're at it. Those are fifteen bucks each for the big ones.

    Yup. I'd wire it to three conductor pretty quick.

    Yeah, they are too expensive, no doubt. I just recapped my 81 Vibrolux and put orange caps in the power, tremolo and reverb sections and reserved the Fender caps for the tone sections. The difference is not subtle as they bring some nice saturation in that role.

    I used the Fischer & Tausche caps for the filter cap replacements.

    I've got a ten finger bag fulla original blue caps. .022 is the scarce value.

    The tube chart does not correlate to the citcuit, which is a May, 1968 circuit at the earliest. Fender used tube charts until thecharts were gone.....and therefor one cannot take a tube chartat facevalue.
    The biggest red flag I see there is that single speaker, which almost assuredly is an 8 ohm speaker. If the OT is the original 2 ohm OT, then the amp has been run with a 200% mismatch on the high side.....and that is not agood thing.imho ime.
    +1000 on getting the amp 'made right' by an experienced tech.

    You are lucky, my Super met with a table saw 40 years ago and became a head, you at least have one speaker and most of the cab!

    I didn't know Fender sold coupling caps. Just took a look and they do for about 15 bucks a pop. Mallory 150s what 2 bucks a piece?

    Don't think I'll be a regular customer.

    I'm amazed that the speaker held up , or did it? that's a mighty small speaker for a Super Reverb, plus it has to be seriously mismatched on the impedance.

    Is that a 1972 stamp inside the chassis?
    There should be date codes on the transformers and backs of the pots, that will get you somewhere in the vicinity of when it was made.

    It's definately worth fixing up , Super Reverb amps sound , well ... Super!

    I've heard varying opinions on the chocolate brown caps, some think they are just fine.

    YMMV but I'm of the opinion , just get the amp working before you go changing everything out, it may sound fine. If it needs new filter caps that's understandable, but I wouldn't just change every cap in the amp until you actually play it and see what it sounds like.

    I'd love to hear it through one 8" before bringing it back to normal...hilariously terrible idea!

    Get it serviced and put four 10"s in it and you'll know why people love Super Reverbs. I love those early SF SR's.

    That is an odd duck. The bias pot is wired as a silverface, but I'm not spotting the power tube pin 5 and 8 snubber caps from that circuit. Maybe someone took a stab at blackfacing it?

    I'm with muchxs, I'm thinking originally late 60's with some mods.

    Serial should be on the far right when looking at the chassis from the rear...stamped into the metal.
