It may be that I had never seen one of these flat-tube sets in person. And then: a week ago I got a visit from a friend who volunteers with her husband at a thrift store. Periodically they will stop by with a box of stuff that came in the donation box but was not considered saleable. The most recent box included a Kmart table radio, an 80s Ford car radio, an old United electric clock...and guess what? An FD-10A. The batteries were pretty old and leaky-after a cleaning and new cells it worked great!
Now, today there were a lot of yard sales and at one (fundraiser at a fire company) a vendor had an FD-40A. He was trying to clear his inventory so it cost me $1. Not as nice a shape as the free one, but decent enough and it also works! The tuning string slips so I couldn't quite bring in a picture. I was hoping these portables would start showing up cheap...I wonder what kinda color sets my start showing up? Should be an Indextron out there...

As for the color sets, suddenly I stopped seeing the 5" early Trinitrons. It seems like the bulk of those went on eBay a few months before the switchover. I am seeing more 8" & 9" Trinitrons from the 90s, and a bunch of later model cheap LCD color pocket sets. I have picked up three of the Sony FDL-310 color LCD Watchman sets; the first Sony flat LCD color set. Amazingly, those are sleepers! I paid below $40 for a new-in-box one, and $.99 for a working but scratched up one. I probably will try to get the rest of the color Sony Watchman series. I do have the FDT-5BX5, which is a Sony rebadged cheapie 5" CRT color set, which for some sad reason, is underservingly named Watchman. It's not even a Trinitron tube copy. Just a cheap Chinese tube.

Back around 1980, RCA was kicking around the idea of building color CRTs shaped like these, but about 20 inch diagonal screen size. Saw a demo prototype mock-up of such a tube in a TV cabinet, but never saw one working. Advantage would be a shallow cabinet. It never saw production. Convergence would be fun...

I picked up a nice Sony FD-10A a couple of years ago at a garage sale for $3. It has the curved tube and works perfectly.
What might be interesting is to build a TV around the CRT's used in camcorders. They were smaller screens (some less than 1") and could probably be used for oscilloscopes as well. It should have all the HV and deflection circuitry, so most of the job is done. Maybe we should have a contest: the best TV or oscilloscope or panadaptor or any other design of a useful product using these small tubes. |

Most camcorder EVFs are completely self contained video monitors - all you have to do is feed them either 5vdc or 12vdc and a composite video signal and you are all set. I built several of these, and have a lot more in my collection to complete someday. I used to buy junked video cameras and camcorders from local electronics junk stores, but now those stores are all gone, so I get my EVF modules from eBay. My favorite EVF comes off old Magnavox VR8276BK01 Color Newvicon Video Cameras because they are completely self contained and detachable with a built-in factory cable and connector. The only thing that they do not have is audio capability. |

I wonder how well these flat tubes would've worked as beam index tubes...

I have a few Zeniths that were built as monitors that were used in police cars for the dash cameras. No tuners, just an RCA plug for composite video.

I have found a few more of these TVs recently... I think that I have a sample of all of the CRTs used in these sets.
04JM... nearly 4" diag. curved phosphor screen. 03JM... slightly over 2.5" diag. curved phosphor screen. 02JM... nearly 2" diag. curved phosphor screen. ED15... nearly 2" diag. flat phosphor screen. Pictures attached. Anybody know of other screen sizes/designs? jr |

RCA ran a great ad in the "trades" back around 1970 or so. It was for their components business and had a tagline of something like "if you can dream it up, we can sell you the parts to build it". It shows a mock-up of a CTC-53 style set, but flat. Gotta dig that out and scan it someday.

I remember seeing a much larger display mounted in Los Angeles police cars in the 1980s. I don't know if it was a lollipop tube, or if it was a reflective system like a Philco Safari. They were used as "MDT" units; the first onboard communications computers for the LAPD. They might have been 8 or 10 inch viewable screens. Definitely not a standard CRT, and not any type of LED or LCD.
Any police officers on AK who might know, or who might remember more details about those 1980s MDTs? Charles

BUMP!
Sorry for the bump, but I would like to ask if anyone has an EXTRA CRT from a Sinclair TV lying around - I would love to add 1 of them to my collection. Thanks. |

I spotted a NON-Working Sinclair TV on eBay several days ago that I thought might be a good tube donor... but the darn thing is over 100 bucks now, with more than 3 days left on the auction...Yikes!!
