Philips X25K121
After 10 years I put my hands on this beast: it was the first color TV sold in Europe in 1966-67. It's a full tube set and today is extremely rare, especially in full working conditions.
The first Philips colour TVs from a 1967 leaflet: rear left the 21KX100A used for the experimental NTSC and PAL transmissions, rear right the model with the K5 chassis with an improved electronic design and the X25K121, the first commercial set. https://i.imgur.com/7ikVE6Q.jpg This is a Philips X25K121, the first commercial color TV sold by Philips in 1966-67 and overall the first TVC model sold in EU. From the top the commands are for: - Volume - Brightness - 6 preselected channels - Color on/off switch - Power switch - Contrast - Color saturation https://i.imgur.com/VQgq1xb.jpg The Philips K6 full tube chassis https://i.imgur.com/afVxZ9C.jpg Audio and color processing circuits. The data on the PAL delay line says that this set was built in 1968 https://i.imgur.com/599dvfH.jpg Vertical and line oscillators + vertical output circuits https://i.imgur.com/ic4pSTp.jpg High voltage cage with the line output transformer.

Nice set!
Good to see you back Komet. I'm actually employed by Philips presently...If that continues for a decade I might have to find and import one of those roundys in the background.

That roundies... The 21KX100A with the experimental K4 chassis was a small production, about 150 sets. It uses a sub chassis for power supply and deflections and another one for the signals, the color demodulation was on a printed board probably for being easy to replace. About 10/15 sets are known today. The other one, with the K5 chassis was only a prototype, nobody know its fate. Yes! Probably I will replace only the booster capacitor for safety reasons. |

*Finally* I found the first color tv I ever owned as a teenager. I bought it for the symbolic price of 1 Dutch guilder at a flea market. It must have been about 20 years old by then and it did fully function, but the colors were extremely dull. After a few years of enduring that I attempted to 'repair' it with a super strong magnet that magnetized the shadow mask and well, the problem with the dull colors was gone..
Ended up tossing it into the local waste recycling trash heap, still feel bad about it! |
