Thanks to all who've responded. I think I have a valid sale going
through and will contact other interested people--several are
in line already--if it does not materialize. --gn.
These were recently removed from a Losmandy G11 during a recent
upgrade. There was and is nothing wrong with them, they were tested on
a dsc computer before and after removal. These are the encoders
only, no circuit board or other hardware.
US Digital sells these new for about $55 each. This is the basic
no bells, no whistles S1 512 encoder, no ball bearing, etc.
On the G11 these are geared to 4096 ticks per revolution, if you're
adapting them to a dob or other mount I'm not sure how it would
work out. You get the nut and washer that comes with all US Digital
encoders but how you gear the axis is up to you. This is the standard
default non-metric shaft whose exact diameter you can look up on the
US Digital web site. Encoders on G11 installations have their connectors bent
at right angles relative to the position of the connector pins as sold
new. If you use these you'll either solder the connections on
with the right angle as is or bend them back.
$35 for TWO includes CONUS shipping. One final note: Don't buy
these if the information in this paragraph doesn't make sense to you.
These are parts for a tinkerer who knows what he's doing.
