NOS 4" b&w from Ali Express
So I saw this bad boy being posted about online and decided to order one. They are apparently either NOS Toshio or Sony sets (probably a clone?)
Only 10 bucks, but 26 with shipping. It's my birthday, a bad one. One that ends in a zero.. so I saw this and bought myself a present. Wish me luck, I'll update when i see how good or bad this lil cutey really is. https://www.aliexpress.com/item/1005002004999718.html Last edited by Airedale; 09-15-2022 at 11:03 PM. |

CRTs still live in 2022! It will be fun to see how well it works when you get it.
$26, don't you deserve more than that on your "F-word" or "S-word" birthday? (Or is it an E word or N word?)

Giant "B" and the part number on the PCB scream Sony but
it just dont look Sony. May be a complete Chi-Com copy down to the markings. Interesting...... Happy BD ! 73 Zeno LFOD ! |

That's a CCTV and intercom for an apartment or office entrance.

Magnavox had a 4 inch CRT set called an Escort back in '85 or so. I see them on Ebay and there is even an Escort 2. The prices are about what you paid.

Well, it works very very well if there are no magnets around. |

Pretty cool..I wonder if the CRT is interchangeable with Sony and other sets with the same CRT size...

Hi to all,
The Chinese 4" flat CRT type 04MC has a TOSHO "made in China" label, see photo. The Sony 4" WatchMan model FD-40A has a 4" CRT designated as 04JM, see extract from schematic. Questions: - does TOSHO manufacture in China using a Sony licence? - unlicenced clone? Unless the Sony patents have already run out, i don't see Sony sitting back doing nothing if someone stole their design. From memory, WatchMans appeared circa 1983, so +20 years forward the patents have indeed expired. Best Regards jhalphen Paris/France Last edited by jhalphen; 12-05-2023 at 07:43 AM. |

I remember seeing something a while back saying that they would no longer support their analog products. So, most likely, they don't care.

That looks like the same one that Adrian Black on YouTube did a video on:
https://www.youtube.com/watch?v=8cU9x23w4YE He has the schematic in his video, which should help you get it hooked up. |

Neat. Looks like it's 50hz PAL. Might be interesting getting a NTSC signal into it
