[TowerTalk] Help with rotor valuation, Telrex

[Matrin Sole]

Thanks Dave,

Yes, that's the one Ha, well it was early last year when I first came into
this great pile of stuff, sometimes you have to invest when you spy the
Alpha 77 in the pile! So I'm just working my way through it. Sold of a lot
of stuff but the rotator seems to have sat  for a while, time to get it
moved.

I'd rather forgotten some of what came out of that thread, indeed I think
there were a couple of messages I missed altogether so thanks for the
pointer. Think it gives me enough to work with and will try to sell locally.
There are a couple of 'big' antenna stations in this corner of the world.

To refresh memories, you asked about this one last year (ain't google
great), and posted a picture at: http://tinyurl.com/78r5nk8 And there is a
thread in the archives describing it:
http://lists.contesting.com/archives//html/Towertalk/2012-02/msg00399.html

If the selsyns and motor work and there isn't too much play in the chain
drive I would probably pay $500 for it if someone had it nearby and I had a
use for it.  Without a pressing need for it I might invest $250 and spend
some time cleaning it up to resell.  It will probably need to be cleaned up
and painted, and maybe have the gear boxes opened up to check for
lubrication and make sure there isn't any water damage in them.  The motor
should also probably be checked.  One big problem with some of the old
telrex rotors is that they only fit in BIG towers, you can't stuff them into
rohn 25 or similar towers, and they are kind of a waste for small antennas
anyway.  This kind of limits the market for them.  The use of selsyns also
limits the use of after-market controllers, you have to refit them to use a
pot for indication or use the old controller.

I have a large rotator that I am trying to find information on and some idea
as to value. Since it is really too big for anything I might ever have I
will likely dispose of it if I can figure out a reasonable value. Weighs
about 40kG so unless you live in Thailand I don't think this is for you.

It is a Telrex A3695RISX, that's what it says on the model number label.
Weighs about 40kG, large 1/3 HP Doerr motor driving a 3.5 inch output shaft
by way of two worm drive gearboxes and a 1 inch wide chain. Direction
information is from a General Electric Selsyn  coupled to the drive shaft by
a small chain. The whole thing is mounted on an 18 inch by 10 inch steel
plate.

Anybody know anything about these, have any info, or care to offer an
estimate as to likely value?

Thanks
Martin, HS0ZED
