<div>At one time I had a Microtime analog TBC, based on switched delay lines, that was supposed to handle Quad video. It had a meter on the front panel. It was a gargantuan beast, about six or seven rack units. Not sure of the model number, but it was a predecessor of the all solid state units. I never tried hooking it to a quad to check out that function. It was squirrely and glitchy by the time I encountered it. </div>

<div>I experimented with feeding demod out of a VR 2000 into a Sony BVT-1000, which was intended for their BVH-1000 and it would make good pictures within a range of errors, but it was necessary to have a pretty good match in the head geometry between the tape and the machine. If you made a recording and then played it back, it worked most of the time, but if you tried to put up any random tape, you would get errors at the edges of the head passes . . . It wouldn't be practical without some additional processing internally. </div>
