A Little Flat Tube Fun

[amptramp]

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.

It is a 1/2 inch B&W EVF CRT Assy - a very popular camcorder tube.

As far as I know, the smallest standard color CRT is the 1.5" tube that Panasonic made and used in the CT-101. I have not yet found a video camera with a standard color CRT EVF. RCA made an EVF with a 1.5" color BEAM INDEX CRT, I have several of these units.

Nice! I guess that I will have to look for one of those.

As far as the "contest" goes I think that Panasonic is the leader right now with this 1982 1" set (shown next to a D 5-100 W tube from a Sinclair portable). I once saw one of these installed in a dollhouse... The tube face was inside one of those "TV" salt & pepper shakers, with the end passing through a hole in the wall to an adjacent room where the circuit board was placed...very cute!

Pardon the condition of the Panasonic... it was my "rooftop" set for many years, and it once took a slide down a tile roof to land on a concrete sidewalk about 10 feet below...ouch!

Your TV is a TR-1010p - I have all of the Panasonic mini CRT sets except the TR-001 - I have the TR-1000p, TR-1010p, TR-1020P, TR-1030p, TR-1031p and the CT-101 color unit.

I collect all kinds of mini TV sets - CRT and LCD, and I am fascinated by the micro camcorder CRTs. I would love to get 1 of those Sinclair CRTs - I never bought 1 of those TVs, but I used to look at them in the store windows years ago - I preferred the Panasonic models over the Sinclair, they looked modern compared to Sinclair's old style design.

I think that amptramp wants to actually build a TV set out of these micro EVF CRT units.
