Yes, Philips is wellknown for a good picture quality. Last night I worked on the Saba. The flyback and high voltage units are working well now. The missing sync depends on cold soldering points in the sync signal separation unit. Now I have to fix the vertical linearity. My son likes the heating tower of this set very much. At lunch he will make fried eggs on it.
To Sandy G.: I didn't saw "Outer Limits". Is it a movie or a TV show?

TV show.-Sandy G.

Awww, man, that's great ! Too bad they didn't have the "oscilloscope", too....Which were y'all's favorite episodes? I liked "Zanti Misfits" & "A Feasability Study"...And the MUSIC...NOBODY did that pot-boiling, OMIGAWD,SOMETHING'S ABOUT TO HAPPEN better than Dom Frontiere, IMHO.-Sandy G.

"The Galaxy Being" was the name of that episode, I think. One cheesy EFX in that one was, it's 1963, right? Well, they show a car turning over, & the car is a late '30s-early '40s model...Possible, but improbable-the people in the car were all dressed up, but in '40s clothes, & the car looked brand new, not some 20-25 yr old clunker.-Sandy G.

I'm not aware of many consumer grade US sets with 2 HV transformers from back then. We did have 2 horizontal output tubes though on some sets.

Typical HV box on a US color sets was: the output tube, which could be any one of a variety of types, the flyback transformer - RCA and Zenith were different in design here, the HV rectifier, inevitably a 3A3 if it was an RCA based set, the focus rectifier - this got you your 5000 or so for focus - 2AV2 was one of the more popular ones here, 1V2 too, and the famous 6BK4 shunt regulator. Oh yeah and a damper of some sort. HV for focus was basically the kickback to the horizontal output tube's plate, the HV was stepped up in the normal way. RCA had the 3A3's plate plug directly into the transformer starting around CTC-15 or so. Lift the HV box cover and the tube pulls out with it. I'm guessing this was a safey feature....

The HV went to the tube and to the plate of the 6BK4, which was a fairly tall octal tube with a plate cap. The 6BK4 would keep the load on the HV system constant at all times, which of course kept the HV constant. I don't think the focus ever had regulation or even if it needed it....

By the end of the tube era, Sylvania and a few others used triplers that got rid of the 6BK4 and 3A3 and 2AV2, and of course their well known X ray issues.

Cathode current on most old US roundies based on RCA designs should be kept as low as possible, I think 220MA is the magic number where they start melting.

There were a few regulators besides the 6BK4 - I think GE made them, but all are beam triodes save for that bizzare one in the 50's. I think they all were compactron or octal based. By the time small portables came around, the pulse regulator method and other methods came into use, though I seem to recall RCA using 6BK4s on some sets right to the end, I suspect because they were really good at it or they just had a lot of them...

Zenith dropped the 6BK4 around 67 or 68 they used pulse regulation.

A technical documentation (only in German for now but with a lot of photos) I have written yesterday. See:
http://bs.cyty.com/menschen/e-etzold...T2000color.htm
The remaining failures are fixed now. The set had a very bad crt with no emission on the red gun and very little emission on green and blue. With a crt regenerator the crt could be activated again. Now I have 0.85 ma on the blue gun, 0.9 ma on the green gun annd 0.85 ma on the red gun. What is your experience with the lifetime expectation of a regenerated crt?

Not really long, it can go from a couple of weeks to 1 year at the most. Old tubes tend to be more robust though.

Babel Fish stinks. ;-) When I have enough time I will provide an own translation, which is better than Babel Fish. If you want to help me you can read my translation when I have done it and you can tell me improvements and corrections. Would you do that?
BTW: I'm running a guitar course in the internet. It is only in German, but I know that many English speaking people use Babel Fish to translate it. They are so happy that Babel Fish exists.

I know i would love a translation of the site to English. I know americans, myself included, tend to not be too keen on learning a second language. I give great respect to anyone who can speak more then one language well, as you can. Id love to be able to read the page in correctly translated english instead of justlooking at the pretty pictures and feeling like the ignorant one language speaking guy i really am. :)

Great job, yagosaga. :banana:
In Romania there where manufcatured Romanians tv sets with a case like that, but they where b & w.
As soon as I can I'll try to put some pics with my Telcolor 3007.

I have tried the translation and Bob Gary was so kind to see it though and do some corrections and improvements. Thanks a lot to Bob!

We had many wooden-case b/w tv sets in the 1960s too. Some of these sets are so similar with the colour tv sets that one can't see which is which. I love that wooden tv sets! BTW: in the next weeks there will be a heavy color roundie on ebay which was a test monitor for colour television attemps in the television set factury in Stassfurt, in East Germany in the midst-1960s.

To avoid misunderstanding: that's not mine. I was in contact with the tv engineer who will sell it.

Wow: an GDR made roundie!

No. It's anm U.S. made roundie. The G.D.R. had imported U.S. color roundies in the early 1960's for testing NTSC as an alternative to PAL and SECAM. This roundie remains from the European battle of colours.
It is the same reason why you have color roundies in Romania.
