It controls the lens turret and aperture plate changeover. As all the cables were cut I wonder if anyone has any connection info. The only label on the card says 'REVOLVER'.

What I can tell you is the pot adjusts how long the motors run for, the idea was you tweaked it to run just long enough to change both lens and plate. Good luck!  |  IP: Logged Ian Griggs Film Handler Posts: 30 From: Lithgow, NSW / Australia Registered: Jul 2016 posted 10-01-2016 12:41 AM                     Steve I have this board as well. Mine is all connected up and working if you'd like me to trace the wiring. But this should all be in the manual. Of course there's always the "armstrong" method IE changing by hand, unless you want to run this off the film.  |  IP: Logged Steve McAndrew Film Handler Posts: 95 From: North Yorkshire, UK Registered: May 2015 posted 10-01-2016 03:46 AM                     Hi Ian Thanks for the reply. I think I am getting somewhere with it. Does your board control both the lens turret and the aperture plates? I am just wondering why I have the extra relays on the small board? Thanks  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 10-01-2016 11:07 AM                     The board does control both plate and turret. I suspect the extra board with relays may have been used to control masking simultaneously.  |  IP: Logged
