Ok, the quick story- This was a 'freebie' I was given a few years ago - 21" rectangular tube, Bakelite tabletop set, with UHF tuner. It sat on it's side in the guy's backyard for a few years prior, looked like a total loss - a mouse moved into the chassis, etc.
I've been playing with it, and here's what I've got so far: * A dead 21EP4, thanks to someone with a hammer. ![]() * A nice bakelite cabinet, but a few missing knobs. * A now cleaned up chassis. I've got reception on it! I can get low VHF channels, with audio, and I've got picture. I've used an 8DP4 that's wasted (I need one of these too) as a 'test tube'. Not perfect, but it's ok enough to get the basics down. There's sweep, and a picture. I recapped the bulk of the set, and I've got lock on both the horizontal (good) and vertical (good enough). And it's stable enough to watch the set. The picture looks all there, and not much noise, though I've got something noisy in the set. Ok - here's the deal though: * I need a 21EP4. * The high voltage isn't. With the listed tube (6BQ6) in the horizontal, I get a rip roaring 10kv, at best. Now, if I slip in a secret weapon, a/k/a a 6DQ6, I get about 20kv with no CRT plugged in. Now, I know GE did running changes to this set (oh, did they do changes!), could they have changed the horizontal tube and not marked it anywhere, or am I looking at an actual horizontal problem (Or a sloshed horz output?)? I'm going to temporarilly pull my only 21EP4 and install everything into the cabinet and see how the set looks, but it's a really dim tube. It's slated for a rebuild, but I still need another tube, because the one that came with the set got wacked by someone's hammer... I'll see, if the tube swap and HV thing gets fixed, if I can post up a pic or two. It's at least working, which is something for a set that sat under a bush upside down for a few years.... |
