If the relays need replacing, you might consider replacing them with "solid
state relays." A led optoisolator triggers a triac device to control power
to the load, I have used them in the construction of 13.8V linears with
excellent results, suspect they would work well for this application too.
They are commonly available for ?-100 amps @ 220V, a search of the web
should provide you with ample sources...

I recently purchased an old crank-up motor driven 60 foot tower that I
would hope someone could id for me. The motor belt drives a gearbox,
which turns the cable pulley. It has a approximately 1 foot by 18
inch control box which has two high current relays and two glass
contained relays. The glass-contained relays are in old 8 pin tube
sockets.

The tower, itself, is in good shape. I would like to re-build the
control circuits and out the tower in service. Any information anyone
can give me on this tower will be greatly appreciated. See at
