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:-

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?
