Author Topic: Unsteady Sound Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 08-14-2005 05:56 PM                     I have generally found that if I use my finger to hold the film on the hold back sprocket until the tension rollers settle, it will run indefinately after that (using the idler roller). As to the tensioners dancing, another cause is the older style rubbler coupling on the Direct Drive models swelling up (CG-629, if I recall). Check the coupling regularly to avoid that problem.

Another wonderful innovation run on a speedometer cable barely big enough to run the soundhead, much less the 6000 Ft, and 70mm reels prevalent in those days.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-15-2005 11:46 AM                     The original R2 soundhead was a direct drive system as well back in the 40's as part of the "master soundsystem"  |  IP: Logged
