Author Topic: How to modify an Ultra Stereo Pre-amp? Matt Close Expert Film Handler Posts: 226 From: Hervey Bay, QLD, Australia Registered: Sep 2001 posted 04-01-2004 06:07 PM                        Has anyone managed to modify the pre-amp card in an Ultra Stereo JS 5/95 to give it a variable slit-loss correction? With the conversion to LED, the top end is excessive to say the least, and these pre-amps have a fixed compensation Any ideas? .... I'm guessing Mark G will know something  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-01-2004 06:14 PM                     You must have a very old preamp card there. I have not run into this problem as most of the units out here have the later style card in them that have slit loss adjustment. This would be best answered by Clint Koch at USL as to weather your card can be updated or not. I would suggest you e-mail him directly through USL's web site.

However a newer 100 or 200 series preamp will get you what you are looking for. E-mail me and we can get something in the works. clint@uslinc.com  |  IP: Logged Matt Close Expert Film Handler Posts: 226 From: Hervey Bay, QLD, Australia Registered: Sep 2001 posted 04-01-2004 07:38 PM                        Thanks Gents ...... I will talk to the owner of the unit and then e-mail you (Clint) if he wants to go down that path.  |  IP: Logged
