 I have a PST61 turning a 6M11JKV (69ft boom) I say I have a '61, but what version?  My impression on Prosistel is that designs changed along the way, but model numbers remained. I contacted the company looking for details about my pst61. They couldn't help other than say to send the unit to them for repair. Control units are the same, and in my opinion, all fitted with transformers that are running at their rating limit. Across 6 rotators, we've had 5 transformer failures. 

As to the pst61 itself. I have pictures and details here:- http://gd0tep.com/pst61/PST61.htm

Hope that helps...

Ten years ago, when I was looking for a very heavy-duty rotator I read reviews and emailed several people with Prosistel and other large rotators turning large antennas. I went with a medium K7NV prop pitch and never looked back.

I’m considering one of these with the Green Heron FT21 controller & 500ohm pot conversion for my next project.  Looks like a good price for just the rotor compared to others.  But I can’t seem to find anyone over this way who can give feedback on their reliability?
