I have a Tri-Ex LM-470 motorized crank up tower. I would like to be able to
remotely control it from my ham shack. The only remote control system that I
have been able to find is the original system that was offered by Tri-Ex. My
concern with that system is that it uses (GASP) vacuum tubes to provide the
delay required when changing directions. Does anyone out there have a
schematic or other information on a more modern design? I have the
facilities to fabricate anything needed, or I would be willing to purchase
an existing system. Any suggestions?

Thanks for your help.
