Author Topic: Alpha Platter issue Jeff Knoll Film Handler Posts: 26 From: Oakville, Ontario, Canada Registered: Feb 2002 posted 07-16-2003 03:51 PM                        Hello All, I have a question that perhaps somebody may have the anwser for. I have a Potts 35MM Alpha Platter (3 tier) and it appears that the transformer in the variac has a few bad spots where the power dies. Is this a part that I can source locally or do I need a genuine Potts part?? Thanks Jeff  |  IP: Logged Paul G.

If it something to do with those, its a cheap fix  |  IP: Logged Greg Pauley Expert Film Handler Posts: 173 From: Huntington, WV, USA Registered: Jun 2000 posted 07-16-2003 06:44 PM                        Jeff, Have you pulled the transformer and looked at the brush that makes contact? This would be the first thing to check before spending money on a new transformer. Also, in case you didn't know the makeup table uses the same transformer in case you ever need one for an emergency.  |  IP: Logged Marc Jones Film Handler Posts: 82 From: Elizabethtown, KY Registered: Jun 99 posted 07-16-2003 10:21 PM                     When inspecting the brush look at the contact on the bottom of he disk I have seen this fail also, BTW anyone know the part number for the contact? Thanks  |  IP: Logged Rick Long Jedi Master Film Handler Posts: 759 From: Toronto, Ontario, Canada Registered: Nov 1999 posted 07-16-2003 10:59 PM                     I beleive that the part number for this is; 2103 Contact Assembly Variac (Staco 1010). 2103 is the Strong number for this item. The typical symptom of this part going bad is that the elevator on the platter tends to "hunt" at certain times during the presentation. Repair is relatively straight-forward, requiring a soldering iron, solder, a slot screwdriver and a set of circlip pliers. Be sure to replace the washers in the order that they came off (usually a copper one, a black one and a red one). Be aware also, that if stuck, you may find this part locally at electrical or electronic distributors who sell Staco - variac components.

Some other threads were saying yes and no.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 12-12-2006 10:37 PM                        70mm is no problem with the correct rollers.\\BTW: won't work on 5 deck platters.

Thanks for the info. So, how come the 3 decks can run it, but the 5 decks can't? Is the only thing that needs changing the rollers/payouts, or do you need to time it too?  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 12-13-2006 04:13 AM                     5 deck units - don't have the clearance for that big of film to pay out decently enough to the rollers on the tower in as well with the rollers on the brain-as you can see here on this Christie setup..The brain's rollers stands up pretty tall using 70mm payouts.  |  IP: Logged Andrew McCrea Jedi Master Film Handler Posts: 645 From: Winnipeg, Manitoba, Canada Registered: Nov 2000 posted 12-14-2006 11:52 AM                        Thanks!  |  IP: Logged
