I found this K9 in the trash on saturday. The cabinet is in unusual good shape, i would say 7 or 8 of 10. Actually, the only damages is some scratches on the left side, most of them probably made by me when i lifted it out of the trash container (it weighs about 80 pounds!). It powered up immediately with a reasonable good picture when i plugged it in, but the green beam was not working. It turned out to be a broken switch on the convergence panel. It was probably shorted. In my opinion this was a strange problem, but i just removed the switch and soldered a wire in its place for now. I have a K9 parts set where i can get another switch. I made some minor adjustments to the focus and color balance, and the picture on the A66-410X Delta-gun tube became bright, crystal clear and with great colors. I gave the entire set a good clean on the in- and outside, using compressed air and window cleaning fluid/alcohol-water mix, and now it looks almost like new. The K9 chassis has a push-pull line output stage, which i have never seen before. I also has a touch sensitive all electronic channel selector with 6 selections, the last one is a VCR-channel. The sound system consist of a push-pull amplifier with separate bass and treble controls, driving the usual Philips speaker configuration; separate woofer and tweeter, and if that isnīt good enough there is an external speaker connection on the backside. I am not sure about the output power, but i would guess somewhere between 6 and 10 watts. Anyway, it sounds very good, like an old Philips usually does.

Good goin', Lars, & another old veteran saved from an ignominious fate....<grin>

I found this K9 at an animal shelter...

I'm sorry... couldn't resist. :D

But seriously, cool looking set!

I always really liked the look of those sets. I know of no American manufacturer, or imported set to the U.S. that look like one of these. The closest I had seen was a multi-standard set my sister picked up in Germany when she was stationed there. It, of course, got a cracked board on the ride home, and ended up having to be discarded. That's a really nice set.

I haven't seen a K9 like that before. The K9 was one sets available when color started here in 1975, but the ones sold here were a lot plainer than that set.

I haven't seen any K9 in a long long time. The days when they were when they were everywhere are long gone.

The K9 parts set mentioned in the first post is one of the "plain" ones. The cabinet has a much cheaper look; the woodwork is not so well done and the frame around the CRT is made of plastic. The ch selector is of the mecanichal push-button type with no lights or other fancy stuff. The sound is not so good either, but that may be caused by dry caps.

:lmao:

I like the design of the chassis. Opens right up and you can get at everything.

I guess this has to be one of the "plain" ones. This was my K9 parts set until this evening, when i stripped it for parts and junked the cabinet and CRT.

That is closer to the models that were sold here. I think the earlier/cheaper ones (from memory, I could be wrong) had VHF only turret tuners. Later/more expensive models had an UHF/VHF 8 channel push buttons tuners (or was that the K11?), though at the time there were only 4 stations on air and none were UHF.

Sounds very K11 to me. The K11 looks very similar to the K9, the main difference is two more channel selectors. Technically, the biggest difference has to be that the K11 has a in-line tube and far less convergence adjustment knobs. This K11 har a plain cabinet, but i have a parts set with the "expensive" cabinet, but that cabinet is unfortunatly behind repair. It doesnīt power up either.

That is the set that I was thinking of. They used to be very common here. You certainly have quite a collection of Philips sets.

Here is a tiny picture (the only one I could find online) of a K9 with a VHF turret tuner.

One reason given for the turret tuner is that no imported tuner could receive channels 3, 4 and 5 (no longer in use) which are between 86MHz and 108MHz.

I have 9 Philips sets (the production years are estimates):

A late 60s FM radio/TV-combo, partially transistorized, not sure of model#, nothing of it works.

The K9 that started this thread, probably made in the mid 70s

1978 K11 22", basic model.

1978 K12 standard version

1979 K12 Hifi with electronic CH selector, blue gun dead, but i have a working CRT waiting to be installed.

1983 K35(?) Stereo with a lot of leaky caps, but works good when warmed up.

1985 K40 Hifi mono with teletext. The remote control is loaded with original Philips batteries from 1983, and they still works!

1984 K40 Stereo with teletext

K40 "FSQ Vision" 21" with stereo and "Computer controlled TXT"/teletext. Not sure if this is a "pure" K40; the chassis looks a little bit smaller, but the layout is exactly the same. The cabinet is all plastic with the CRT mounted on the "inside" of the frame.

I also have a perfectly working VR2020 Video2000 player and a Philips VR6542 VHS.

Hello,

yesterday I have rescued a Philips Goya 110L (D26K160 06) color tv set from putting into trash without paying one buck. Since two years I have searched in the whole country for such a set but without success. Yesterday I got an email from the neighboring village (!), somebody will move and has this set in the cellar. And before putting it to the local city dump, he asked me whether I am interested in this set. I made a telephone call and in the evening I brought the set at home.

This was the first color tv set in Europe with a 110° deflection CRT, made in 1971. It is fitted with an A66-140X (0.8mA blue, 1.2mA red, 1 mA green beam current) and with two line output units, each with a pair of PL519 / PY500A. The total power consumption is 400 watts.

The set is still in operational condition:

When I have enough time, I will create a web page about the technical details.

By the way: when did you get color tv sets with 110° deflection crts in the US?

The K9 died yesterday. I was watching a movie when it suddenly got a horizontal collapse, i heard a "zapp"-sound and there was a big spark before it went black. I took a look at it today, and there was a hole burned through the PCB. I fixed it with some wires, but it still doesnīt work properly; It has raster and sound, but it also has a partial vertical collapse, and resistors R483 and 487 gets very hot. The problem is probably in the vert. section, but where? Any ideas? I have the schematic.

I don't remember the exact details, but from memory certain faults in the horizontal section will also affect the vertical section. These faults were detailed in the Serviceman column in Electronics Australia magazine. Some old articles are available at www.siliconchip.com.au, but I don't know if they go back that far (I did find an article on a 1988 JVC set I was working on). I do still have a lot of magazines from the 60s to 90s, but they are in no way organized so it would take forever to find it. The fault may have also been documented in the UK Television magazine. Are there any large technical libraries in your area that may still have such magazines?

I donīt know about any places where i can get info on this, unfortunately. Another major problem is that i canīt have the set switched on for more than a few seconds at the time because of the overheating resistors. When the set failed, i was switching itself rapidly on and of for a few seconds, and i wonder if that may have damaged a transistor somewhere. The fact that there is no elecronics shop nearby isnīt making the case any better. I have a working parts chassis, but it is in my mothers apartment, and it will need all the caps replaced. But now it looks like this may be the most simple solution after all.

Try tracing where those resostrs go. Either there's too much voltage going in (unliekly), or there's something loading down the other side of them. Chances are it's a shorted diode, cap, or transistor in the circuit being fed power through those resistors. If you need to run the set, unsolder one end of the resistors so they don't overheat.

I looked at the schematic now, and the power to the v-amp goes through those resistors and is fed more or less right into the transistors, which is probably shorted. Iīll try to get new transistors this weekend, if not i will get the parts chassis by the end of the month.

I'm from Italy and i have several Philips TVs, with K9, KM2, K11 and K12 chassis (and i've done a lot of work on them)

A common problem with Philips TVs are dry/cracked solder joints, you should never ever use a vintage Philips before checking for bad solder joints on the deflection chassis as this may cause severe damage to the PCB and components and a potential fire hazard

That's sad as old Philips TVs are otherwise real engineering masterpieces...
