Three Phase Supply[edit]

I worked with the VR1000, 1200, 2000 and 2000B and none of these used three phase supply as the article claims. This was with 240v UK mains supply, so perhaps it was different for the US 120v models.

You are correct, UK units were not three phase, as they used half the amps.Telecine Guy 04:47, 7 June 2007 (UTC)

Yes, I had a VR1000 at home in the UK in late seventies (long story). To get it working I had to buy two 1kW 240V -> 110V autotransformers but it then worked from normal domestic single-phase power . My VR1000 only had two racks of valve (tube) amplifiers, servos (KT88), PSUs etc., rather than the three mentioned in the article, and the vacuum pump and compressor were built into the console for 'mobile' use (i.e. in a van (truck)!). I got it working in 405-line then converted it to 625, but unfortunately there was a defective head tip, so every 4th band in the picture was just noise. Fom memory, the whole thing took nearly 3kW as there were a fair number of valves (tubes) in the console as well as the racks. One more memory - the 1950's instruction manual had an amusing cartoon character on the flyleaf called Mr. V.D.O. Recorder! —Preceding unsigned comment added by John Logie (talkcontribs) 10:58, 2 April 2009 (UTC)
