Any one ever played with 1" and 2" V.T.R.'s?
If some one played with a 2", but not Quad sistem, in stad "I.V.C." 9000 he's/she's a president!

Used 1" a lot. Only ran 2" a couple of times, and it was quad. Still have some Hitachi HR-200 service info, I think. And an external power supply for the Nagra/Ampex 1" portable.

I've got an RCA just like this: http://www.labguysworld.com/RCA_TH-50A.htm

I need to rig up a 12V supply for it and put some tapes on it. I got it at the last spring ETF, but had not had time to 'play' with it yet.

I still have a Philips EL3400 here, which seems to be an extreme oddity as all the information I can find about it originated from Europe but this is wired for 120v service. It's been sitting in a rather neglected state for almost two years now because now that I've tried my best to clean the corroded drum up it has to all go back together. Someone gave me a random reel of 1" tape recently however so I guess I can put it all back together as a showpiece. Baautiful hybrid electronics in it.

"Philips" EL3400 was a home use machine.

1" sistem A?

No, it is 2 inch helical scan:

"From 1963 to 1970, Ampex manufactured several models of VTR 2-inch helical VTRs, capable of recording and playing back analog black and white video. Recording employed non-segmented helical scanning, with one wrap of the tape around the video head drum being a little more than 180 degrees, using two video heads. One video drum rotation time was two fields of video. The units had two audio tracks recorded on the top edge of the tape, with a control track recorded on the tape's bottom edge. The 2-inch-wide video tape used was one mil (0.001 in or 0.0254 mm) thick. The VTRs were mostly used by industrial companies, educational institutions, and a few for in-flight entertainment.

The capstan tape speed is 3.7 inches per second, which provided a long record time of up to five hours on large reels. The units were 100% solid state. The Ampex 2-inch helical VTRs were popular, as they were priced much less than the 2-inch quadruplex videotape recorders used in the broadcast television industry at the time."

Intresting.
But how is the resolution?

Better than VHS, about 3 mHz, IIRC. I was told that it was used by a low budget educational station for broadcast of old B/W Alan Watts Zen tapes, but was not quite broadcast quality.
