I read somewhere that such a CRT was built, but it was never used in a TV. I'd love to know if it was true. The tough part would be achieving the near perfect linearity, and razor sharp focus needed to make it work.

Jerome Halphen said that Sanyo made a small TV with this type of tube, and I am certain that I did see a small 3" Sanyo TV in a pink case on a pedestal for sale on eBay a few years ago. I did not know about the Beam Index technology tubes at that time, and did not pay too much attention to that set because it was a Sanyo - I have never been a fan of Sanyo products. I really hope that 1 of these sets surfaces again just to prove that Jerome and I are not crazy!

From Wikipedia:

Sanyo used the bright images to make a new style of tube they called the "lollipop".[12] It used an electron gun arranged at right angles to the display, extending down instead of to the rear. The result was a 3 inch display only 1˝ inches deep, although it was several inches long. They demonstrated the system in a small television similar to the Sony Indextron.

Reference 12: David Lachenbruch, "super-TVs", Popular Science, July 1985, pg. 66 ("Apples and lollipops)

I have 2 of them Sanyo sets, & as far as I know, they have conventional CRTs...One of mine is Pepto-Bismol pink, the other is ivory...IIRC, they also made 'em in silver & black. Cute l'il fellers-One of mine needs new caps/attention in the horizontal section...They DO have v. good pictures when working properly.

Sandy G - Can you please post a picture of the set. I do remember exactly what it looks like. I can't be sure it was a Beam Index - Jerome believes it is, and that the model number is 30-CTV1

Are you perhaps thinking of the Sharp?... Phil restored one here:

I just got one in ivory.

jr tech - I did see that model Sharp on eBay several times, and I do know that it is not a Beam Index - but, I also did see a similar Sanyo with a completely different pedestal.

Cool! Did you once indicate that several viewfinder CRTs were beam index? I assume that these were not lollipop designs, however.

jr tech - Yes, the color CRT viewfinders on the old RCA cameras were Beam Index with a Hitachi made tube - standard CRT configuration, not lollipop design.

Also, here is a link to the Popular Science article that I referenced in an earlier post:

http://books.google.com/books?id=lQA...extron&f=false

You have to scroll up to see the TV and lollipop tube - I have NEVER seen this set.

Well, I got confused also, so don't feel bad! I got out my ivory one, turned it on and was convinced that it was a shadow mask tube, and was about to post that the Sanyo had a shadow mask, when I realized the TV might have said Sharp on the base... so I grabbed it again... yup, Sharp!

Hi all,

The Sanyo index tube never made it to market. Only shown as a prototype.

Jerome, Thank you very much for the Indextron Service Manuel and other items. Much appreciated!

I won the auction for the white Indextron. You can see it at my website. Just scroll down .... and you access my entire collection pages 1 to 5 on same site in drop down menu tabs. http://www.visions4.net/journal/test.../page-three-a/

etype2 - Very NICE collection!

You probably broke Jerome's heart with the news about the Sanyo Index Tube. Here is a quote that was posted in another thread by Jerome Halphin:

"Last but not least, Sanyo sold a very limited quantity of the 30-CTV1 4" Beam-Index color TV in the US, 1986. Saw one in the LA area in a pink case, had spent all my $ on a CT-101 and couldn't buy it. Gone forever!"

I know that I saw a set that fits this description on eBay a few years ago - it looked a lot like the Sharp TV referenced above, but with a completely different pedestal. It had a standard style CRT configuration, but I do not know if it was Beam Index. Do you have any knowledge of this set?

Hi Sandy G. Scue me if not up to speed with how this forum works. First off, THANK YOU! Safari: Genius. Sony KV 4000: One of my all time favorites. Panasonic CT 101: Wanted to buy in the day, couldn't afford one. It's amazing, even today. Thanks again, Sandy G.!
