[QuadList] save htis and look tr4 converts to hi band but alsoneed modul...

[David Crosthwait]

Ed,

Congratulations on your acquisition. The TR 5 was a stripped down machine that enabled it to be more mobile. Therefore many of the correction circuits used to fully reproduce a broadcast quality playback picture were not included in this machine. Although the recording will be a good one (if all is working OK), you will only see demodulated video upon play back that will give you a good sense that a recording was made. Without the RCA correction circuitry such as CATC for color time base correction, CAVEC for velocity correction and the color dropout compensator option, the recovered picture (depending on the options used as on any 2" machine) may be raw, flickering color (if color is present). So in the remote truck, the operator upon conclusion of a record session could verify that a recording had been made by playing back this "demod" picture. An analysis of the FM (RF) and control track signals on the scope added further confidence that all was OK. An experienced operator who knew the machine well would have a better sense of confidence than one who was not, therefore being more at ease with a "demod" only picture. It is a bit of a leap of faith to tell the director in the truck that all will look fine upon playback of his show in the studio on a fully optioned playback machine.

Years later when the first portable field one-inch type C VTR's came out such as the Sony BVH 500, it was typical to confirm the integrity of the recording by observing the same "demod" only picture with no time base correction.

Your might be interested to know that the RCA list price for a TR 5 was $20, 950 in 1966.

Ironically, the fellow that owned it found out about  me  after  he  had committed to some one else it.... I tried to call them as  they were driving in to Arizona and offered  them a large  chunk of  money  to turn the truck around to no avail.  we still talk on a regular basis and  he  may be helping  with this  unit, although it is an earlier  one than  he  has  worked on.
