    Hey guys, I want to recap my '72 SVT. It's recently started picking up some of that oh-so-soothing 60-cycle hummmm....
    Where does a brother go about purchasing some of those big-ass electrolytic can caps? I haven't opened it up yet, but looking at the schematic I believe the big filter caps are the 100 microfarad 450V jobbers?

    "Ric", have you ever done a cap job before? If not, I STRONGLY suggest that you let a tech do it. I'm not saying that you can't but an SVT is not the best platform for learning. In my experience, Ampegs are notorious for holding charge (even when unplugged) in their caps and will knock you down fast if you touch the wrong place.

    Enough for the disclaimer, if you know what you're doing, then www.tubesandmore may have what you need. Those old can style caps are getting harder to find.

    Good Luck,

    Thanks Tapp... I've never done a cap job before but I believe I'm knowledgeable enough to pull it off without getting killed. :) I've got an engineering degree and I build effects for kicks, so I've got a little more than a basic understanding of electronics.

    I checked that page out (tubesandmore) - they didn't seem to have the ones I'd need. I also found a webpage ( that sells parts for vintage ampegs, and they even sell a cap kit for an SVT! Problem is, the values of caps they include in the kit aren't the same as those on the schematic. It looks like the voltage rating is too low for most of them... ???
