Hi Gang:

Found this treasure in the basement...................

This is an incomplete US Navy USM-3A Test set.  The USM-3A is a 
complete miniaturized service kit for tube-type equipment and was 
designed for use in the field to troubleshoot and make temporary 
repairs to equipment.   The whole thing fits into a 1 cubic foot 
metal case, the CY703A/U.  The TV-4A/U is a compact tube tester made 
by Weston and does a remarkable job of testing tubes for its 
size.  Also included is the TS-673/U signal tracer and is complete 
with the neat metal box containing the probes and the little headset.

The Technician's Handbook that fits inside the case is also 
included.    I also have two of the neat probe meters that came with 
the kit.  However they are missing the metal spring ring that keeps 
them closed.  I don't know if they work.

Here's what's missing:  The decade resistor, decade capacitor, all 
the tools, the probes, soldering iron.

The TV-4 alone sells for around $200.00 when they surface.  The metal 
case with the signal tracer probes and headphone is very hard to find 
but it appears complete.  I am asking $250.00 for it plus 
shipping.  I know that I could get this and possibly more easily on 
ePay but I'd like to see this rare gem go to one of the R-390 gang.

If interested please reply by e-mail.

73,

Michael, W1RC
