[QuadList] Rebuilding RCA TR-600s

[Don Norwood]

Hi John:

If this were an Ampex, I'd try to help with specifics but I'm afraid I've never worked on a TR-600.  However, I can offer some insight regarding the use of an external TBC.  You need to be aware that there were very few models of TBC's that would work with quad tape.  The vast majority of TBC's were designed to work with non-segmented formats, and consequently they do not work with the quad format.  Perhaps someone has a complete list of models that do work with quad.  The only ones that come to mind are the CVS-520, NEC NTC-5000 and the ADDA VW-2.  There were others modified to work with quad by Merlin and possibly others.

  Steve:

  We did replace those caps (there wasn't a big oil can type.but there were several large caps in the power supply).

   

  We are contemplating using an external frame synch in conjunction w/ the internal TBC.  Any thoughts about this?

   

  Or even using an external TBC.not sure if this would work though.  I did notice one thing.before the TBC adjustments (alignments), the video actually looked better in Demod.but we got it looking better now in TBC mode (which you would expect).as of right now, the picture looks better in TBC mode than it does on the output.yesterday, before the machine went downhill, we had it looking the best on video output.

   

  More to come tomorrow.
