Hi, and thanks for the welcome!
Hippos are easy to work on, and I've now done my second one, which I will sell at a more reasonable price than the first, which I'm still listening to even though it's on eBay.
One problem with the second one, the volume pot is bad, and I need a new one. I took it apart and see the carbon is actually worn off so there is no continuity between the two fixed ends. Getting one with that long D shaft will be a bit tricky, so I started looking for other pots I could maybe take apart and salvage just the wafer with the carbon on it. Well, that ain't happening!
So, the question is, where would one go to replace this pot? I've seen other Philcos with the knobs on top, and imagine the chassis arrangement inside is similar to a Hippo. Is there a chance that some of these use the exact same part? Anyone found, say a guitar amp that uses a really long D shaped shaft? (Those would be easier to find.)
Anyone found an available substitute new? Anyone got a junk Hippo chassis with a good volume control pot? (If the switch is bad, I know I can swap that out with mine, so that's not a problem.)
By the way, I'm stepping up my game, and just won a 49-909, which will sit and look pretty for a while before I get around to recapping it! (There might be a Zenith or two or four that have to be done first.)
