Product Description

This Technical Materials Corporation (TMC)  CV-591A /URR  SSB  Converter for the Collins R-390, R390A , Hammarlund SP-600 & more, is a LATE S/N 4269.

  This one is in beautiful condition. I have not tested this one with a receiver but it was serviced.  I did power it up and it switched the USB/LSB back and forth as it should.

You will notice the large Red L3, a 3/4 Henry inductor on the bottom inside picture. This was added as part of FC 5. It reduces the amount of the 17 kHz IF frequency. This may be part of the reason for the great sound of this unit.

This unit was sent to Rick Mish (Miltronix)  a little over 5 years ago for a complete restoration. The front panel was refinished, the nomenclature redone, and it looks great.

This unit also has the control knobs that match the R-390 and R-390A that was part of the restoration to better match the R-390.

As most know, Rich does a great job restoring the R-390s and the CV-591A/URR SSB converter.

Rich not only does the front panel but also replaces many of the components that tend to go out of spec over the years. The power supply capacitors, and many other Capacitors and resistors, are replaced as a course of servicing them.

Rick is still in business today and a restoration job (as was done on this unit) will cost $500.00 and about $100.00 shipping both ways. He also can service them and R-390s, to fix problems.

I will provide a link below to his Website.  He is ready to service your gear!

The Technical Materials, Inc CV-591A/URR,  takes the 455 khZ IF output from any number of receivers, such as the Collins R-390 or R-390A, or the Hammarlund SP-600. 

I am selling this unit as is as described, for the family of a silent key.

I will provide a reproduction of the manual and the Correct power cord.
