[Elecraft] HeathKit: uMATIC MEMORY KEYER - Model SA-5010

[Ira J Saber DMD]

I was going through some of my stored equipment and ran across my HeathKit:
uMATIC MEMORY KEYER - Model SA-5010.  I turned it on and was refamiliarizing
myself with the unit when it just turned off.  No smoke, noise or any other
problem noted when this occurred.  I disassembled the unit and checked some
connections, replaced some batteries and still no joy.  Does anyone out
there have one of these units?  I would like to bounce some ideas off anyone
who has some knowledge of the unit.  If you wish to contact me off the
reflector, my email address is bomfsa at optonline.net.  Thanks and best 73,
