Author Topic: CP-65 150 card Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 04-03-2015 12:18 PM                     I had a call the other night that a CP-65 was stuck in bypass and they had no sound. It turns out the 150 card went bad. I pulled it out and all was good. Since the 150 card is not needed for digital sound or non sync, should I just pull them out of all the units? Will this help the load on the transformers if removed, or will it cause any negative affects, or it really doesn't matter?  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 04-03-2015 12:31 PM                     It's involved in the Non-Sync signal path, that much I do remember. Anymore I'd have to dig out a dusty old book.  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 04-03-2015 02:41 PM                     Non sync still plays though.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Otherwise, you can live without it.  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 04-04-2015 03:09 PM                     Spot on Steve. I just reminded myself with a look in the book.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-05-2015 10:26 PM                     I pulled everything up to the decoder in all Dolby, Panastereo and USL units. It also makes things easier going on the power supplies. Mark  |  IP: Logged
