Yes we in Europe have plenty of 100 hz televisions. They solved the flickering problem but worsened the picture quality introducing a lot of digital artifacts. A 100 hz picture seems unnatural as compared to a plain 50 hz tv. If you have messages scrolling on the screen horizontally then they often appear doubled making them unreadable...Lcd made things worse. I wonder where all this tv technology progress is but people seems just to look only how fancy is to have a tv hang on the wall...Too bad!!!

I have two 100hz TV's & I find them easier in the eyes then a large screen 50hz set. The first set a Grundig set from 1994 & a 2000 Philips which has a much better picture then the earlier Grundig. The Philips set uses what is called a Falconic chip that avaridges out the 2 fields to minimise the effect of double images with scrolling writing or fast moving objects.
The only thing about 100hz sets is the picture is always softer looking & is made to look sharp by using what is called a VM coil on the CRT neck near the convergance magnets. The basic idea is the feed in the luminance signal & amplify that to speed up the electron beams with the transistion from balck to white & thus sharpen the image.

The NTSC playback on PAL TV function offered on most recent VCR does look awful. Some do have an option to output NTSC when playing back an NTSC tape rather than converting it to PAL. This does look better on a multistandard TV, but I'm not sure that even this is a true NTSC signal as it on one of my Sony PVM monitors it just gets confused and gives a flickering green/purple image.
I do have a 13" Hitachi NTSC only set, but it doesn't have AV inputs so I'm yet to see if it does look better than my multistandard sets. I've never seen SECAM and I doubt I want to. I thought pretty much everyone that once used SECAM had converted over to PAL by now. As for 50Hz flicker, I've only ever found it objectionable on some cheap nasty 80cm sets. I just don't notice it on smaller sets and some better large screen sets, but I guess I am used to it. Most sets will handle PAL at 60Hz and you can get this out of many DVD players and most game consoles. I recently picked up several Loewe sets. I'm pretty sure at least the Calida 5672 (currently awaiting a flyback) is 100Hz, so eventually I'll get to see if it's an improvement. I do have a scan doubler that ups PAL/NTSC video to VGA, but I rarely use it due to the artifacts it introduces.

I am familiar with the 100Hz-problems. In 1996 my grandparents bought a pretty expensive 28" Nokia 100Hz TV. At the time, it was a great set, but to my great supprise it lasted for only 4 years. It had sound, but showed only a horizontal white line on the screen. My guess would be a bad v-(op)amp, i think both Nokia, Finlux and Luxor had too small heatsinks on the v-amps, which by the way was usually placed on the circuit board on the CRT base. Last summer my father bought a used Philips 100Hz widescreen (from about 2002-2003) in the same price range, and it got a much better picture, so clearly something has gotten better over the years. My mother has a Finlux widescreen (50Hz) from 2003, and that is absolutely not a good set. Actually, all my old sets outruns the picture on the Finlux, and most of the old ones has better sound too. Hope the v-amp in the Finlux dies soon...

Early AWA TV on eBay Australia...
Back to the subject on early Aussie TV's, Whilst surfing the net today I found this specimin on eBay Australia.
It is a 1958 AWA 209C with a short neck 17in CRT that was first used in Aust TV's in around 1958 before they went to 110deg CRT's in around '59-'60. http://cgi.ebay.com.au/TV-Radiola-De...ayphotohosting Is there anyone in the Melbourne area that could save this one from the landfill.....

Cool. I had a very similar set years ago. It had the same chassis, crt and knobs, but was in a shorter cabinet with the speakers at the sides rather than below the controls. It was going to be a special project, but unfortunately I had to get rid of it in a prior move. I tried to give it away back then but there were no takers.
If I had more space I'd bid on it. It does have a couple bids, so it will be spared from the tip.

I like the artwork used on the back covers of these Australian sets. Almost ashame to have it facing the wall! Now, what was the connection (if any) between this Radiola and RCA?

http://www.radiola.co.nz/aboutus.asp Looks like AWA/Radiola has been around for quite a while (and in fact been selling radios under the Radiola name since 1924), and doesn't appear to have had any relationship with RCA or Victor. Huh. On a related note, it always seemed kinda interesting to me that while RCA is long-gone in the USA, the old Victor Talking Machine company still lives-- well, their old Japanese subsidiary, anyway (Victor Company of Japan). ...Which we know of as JVC, though they still use the Victor name and "Nipper" logo on their products for the Japanese market. (They can't in the USA, though, since RCA (now GE) has the rights to the Victor name and logo in the USA on consumer electronics products.)

The blue sticker isn't a TV license. It's been a long time since I've seen one, but from memory it is says something to the effect of "This AWA TV is covered by the following patents" and a list of patent numbers.
A connection between RCA and AWA wouldn't suprise me. Their early B&W sets resemble American sets more than they resemble English or European sets. I'll see if I can find any pictures of some of the later chassis, maybe you guys on that side of the pond will recognise them.

I have at least one Radiola radio set from the late 40s, made by RCA, just a plain brown bakelite AA5. I don't know why they offered the seperate Radiola line. (no mention of RCA on the front, only on the bottom label.) (I think it says RCA Radio Sales Co. on the bottom, so I guess a different division of the company sold these?)

have been mostly just to keep the trademark alive. "Radiola" was a name that RCA used on (I think) all of their radios in their early days, but they phased it out that moniker in the early 30's or so. While RCA seemed to eventually stop using the Radiola name, they did seem to recycle the Victrola trademark (which they got from their purchase of Victor) for various purposes from time to time. Seems like all the RCA pre-packaged phonographs from the 1950's-era got badged with the Victrola name somewhere. ...Though that at least makes sense, since "Victrola" was originally supposed to indicate an internal horn phonograph, those would have been the 50's-modern equivalent (though Victor had originally further distinguished electrified phonos with the "Electrola" name). Then at some point, RCA Records took the Victrola name and made it into a sort of "budget" record label for classical music (sort of a low-cost alternative to RCA's premium "Red Seal" classical label). I wonder what happened to the Victrola name after that, though. If RCA was still around and was still manufacturing audio equipment, would we be able to go to the store today and pick up an RCA "Digital Victrola" CD player..? What if RCA had called their Selectavision CED videodisc players "Video Victrolas" instead..?
