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!!

Yeah - I have been watching auctions on eBay for a while, but they get too expensive for a unit just to pull a tube out of. I really do not want a complete set anyway. I thought that if someone has an extra 1 lying around, we could work something out.
The first time I actually saw what the tube looks like was when you posted a picture earlier in this thread - very interesting and even cool looking design compared to most CRTs that I have seen - I do not know if this is so different because it was designed in another country, or if it has any technical benefits. |

I suspect that the small magnetic deflected tubes actually offer better performance. But the "fat neck" to provide room for the deflection plates and the curved screen, which likely reduces deflection defocus make this tube very unique. Do you have a 913? I see them once in a while on eBay.

I have never seen 1 of these tubes - I am going to add it to my wish list!

I found this on the same site under CRTs and Camera tubes. (Don't know how to link to the exact page, but here's the picture)

Cool find! This is a refinement of the Aken tube from the 50s... I believe that work continued through the mid 60s and even a color versions were attempted using various approaches.

For some reason I can't see the picture. But I can if I go directly to the link.

It disappeared from my browser too. I think some people get "funny" about having pictures on message boards etc. That's fine, but then at least design our site so it can be directly linked!

Test... Can we see these?
Added comment...Funny! now that I have downloaded and stored these pix, I can *again* see the pix in the original post, so I guess my browser stores them and supplies them as needed in the first post? jr Last edited by jr_tech; 12-25-2009 at 02:12 PM. Reason: added comment |

More Watchmans (Watchmen?)
Some recent additions to my small TV collection:
1. "sports" versions... CW from 8:00; Green Bay Packers FD-2A, Tampa Bay Buccaneers FD-30A, San Francisco 49ERS FD-30A (the 30As have a decent AM/FM radio built in), LA Raders FD-20A. There are many more Football teams, as well as Baseball teams... I don't intend to collect them all. 2. 2.6 inch models... Continuing CW from 2:00; FD-230 (thick set), FD-270 (nice, thin set) and the weird palm-grip FD-280. 3. Red white and blue FD-10 series... I don't have the white yet. 4. Odd Digital Clock TV/FM FD-3A. Clock is not functional on this sample, so I can't tell if it can be used as an alarm clock radio/TV... anybody here know for sure? jr |

There should be a separate battery to operate the clock on the FD-3A.
