Found a Capehart

Hacker, my experience has been that there's not a whole lot of interest in Capeharts. I have my family's original set, a Capehart 325-F (appx 1951), put a new CRT in it back in the early 70's thinking I'd use it in my bedroom when I still lived at home, but the set had more problems than a new CRT resolved and running it with a shrunken picture only created an uneven burn-in on the new CRT so I abandoned the project. My expertise didn't go much beyond changing out tubes then, and it still doesn't now. The set needs a re-cap at the very least but I have no place to put it once it's brought back to working condition so for now it just sits. Debating on whether it would be easier to sell (if I decide to) in working condition with a recap, or as is. I did put up a post looking for knobs and got a guy who found some for me so you may get lucky with knobs for your set too.

Great catch on the Capehart 333. The picture tube number you're wondering about is 17BP4, still occasionally available on eBay or thru antique electronics dealers. Your set was sold in 1950, and was called the "Blue Ridge" model. There isn't a Sams schematic sheet for it, but the schematic for the 325-F is pretty close. Look for Sams sheet 112, Folder 3 (11/1950). Capehart-Farnsworth put out a set of service documents for it that's more useful, but really hard to come by. Here is a photo of my 333, as I found it. It's currently in pieces, under repair. Until now I thought it was the only one left. Despite the "lack of interest" (some perceive) in Capehart sets, you should give your set the attention it deserves. It's certainly an unusual item practically nobody else will have. I found mine 5 years ago, yours is the only other identical one I've come across.

You might be able to remove the B&W CRT burn in by running the CRT with a full white raster for about 100 hours or so. Brand new phosper will dim about 10% in the first 100 hours or so if use, and then stay about level for the next several thousand hours. The idea here is to get the unused phosper (that which was outside the shrunken picture area) past the 100 hour use to get it about the same light emitting level as the burnt in area.

Thanks for the advice on the burn-in issue. I can tell you right now that this set didn't run for anywhere near 100 hours after the new CRT. It only took it a few minutes for the pic to go all distorted so it wasn't worth watching for any length of time that way.

If I had the room, I'd have this set fixed (I know of local guy who would do it) because I know it would give a great pic and sound once it's working right. I've only seen one other 325-F and that was on eBay within the last several months. Don't know if it sold, or if it did, for how much.

Also, the set needed both the on/off and channel knobs and one guy was able to find them for me. Found that on the channel knob, the numbers only go around it half way, the other half of the knob is blank, as if once you hit channel 13, you have to go backwards instead of continuing in the same rotational direction to channel 2. This is apparently how Capehart designed some of their sets, as even the owner's manual for the 325-F set shows that kind of configuration on the knob, but the actual (and original) tuner on this set rotates all the way around and calls for a knob that has the channel numbers evenly placed around the entire knob, not just on one side of it. If anybody knows where I can find the right selector knob for this set, please let me know: [email protected]

If I do decide to restore the set the tuner will likely stay on channel 3 or 4 so it can be run by cable converter, so the knob issue wouldn't be the end of the world, but it would be nice to have the right one if it can be found. No small task.

Here's a shot of my 325 with a fresh set of orange drops and power caps. A few resistors are still out of tolerance, but it's pretty close to power-on tests. Also, here are a couple of scans of the technical documents for this set. I have electronic copies of them available if anyone is interested.

Hacker, looking at your photos I see the ten-watt voltage-divider (resistor) mounted to the chassis of your set (very bottom of your photo) is broken. You'll need to replace that before you even think about applying power. Catastrophe otherwise. Besides that, the bottom of the chassis looks really clean and you should be able to restore it.

Finally, if either of you two feel like you are going to sell your sets rather than restore them, give me a heads up. Thanks.

KB, just wondering, in your experience with TV restoration, how does Capehart compare with other makes for overall quality of picture and sound? Is it noticeably superior? These sets weren't cheap when new. It's hard for me to judge picture quality on an old BW set. I've become so used to watching bright and clear color resolution on the modern sets around my house, I no longer remember what a B&W set should look like at optimum performance. I have a recapped Admiral 20X12 set that's hooked up to cable with a converter tuner and has high contrast on some stations and low on others (this may be an AGC/DC restoration issue) and when it's tuned to a high contrast station you can't see a lot of detail because objects show up as solid black. I keep controls adjusted to some middle ground so the low contrast stations don't show up with thin diagonal lines, which to me is more annoying than high contrast. Is this typical of early TV behavior or would a Capehart with AGC give steady resolution on all channels? I'm trying to decide if I'll ever want to restore the 325F, and knowing whether it would be watchable and that I wouldn't have to be fiddling with the adjusting knobs all the time would help me with this decision. I've gotta make my case with a spouse who likely doesn't want a hulking cabinet with obsolete entertainment taking up valuable space in the house, so would like to get your opinion on Capehart vs other makes.

I dunno about their TV sets, but Capehart was primarily known for their line of console phonos and radio/phono combinations in the 1930's and 40's. Their biggest claim-to-fame was an amazingly elaborate record changer that could automatically play both sides of each record in a stack-- in sequence-- and still even intermix record sizes automatically. I've seen one of these changers in action once; it's a facinating Rube Goldberg device. The thing was pretty much done in by the introduction of the LP, though, since the original mechanism was designed for 78's only, and while Capehart did eventually adapt it for LP's, the convenience/desire for such an elaborate record changer wasn't as high for LP's than it was for 78's.

High-end Capehart radios were high quality and quite expensive. I believe the postwar Panamuse had 25 tubes.
