Figuring this out…
It’s I assume a variable rate AC drive for the Parks Optical 10” superior telescope and mount I just picked up. Other pictures of the item I picked up are cluttering up the classifields thread (https://www.cloudyni...cope-ads/page-5)
AC input power cable and 1/4” stereo jack connector that goes to the RA motor drive.
has an optional 12V DC input that is also a 1/4 inch stereo jack.
not impressed by the speaker wire used for 120V AC input.
two transformers on top step down 120V AC to 9V AC.
cant find any pictures of anything like it online and I guess it’s home built from a kit.
ill take the bottom off and then cautiously power up from 12v DC and probably delete the AC cable.
I’ve not checked the drive motors on the mount but they are hopefully 12v AC.
ill put an oscilloscope on the motor output to see what’s going on there.
Here's the rest of the find! Thanks to glittledale
