MarkC Posted March 23, 2018 Report Share Posted March 23, 2018 Hello, I have a 35 year old Dolby 372 unit that needs some servicing. I contacted Dolby and unfortunately they do not service their older instruments anymore. Everything on the left channel works but the right channel has a shrill thinning sound when playing back a 320 wBn test, encode in record with NR on has no problem, however, playback "NR off" produces a distorted,/scratching sound. I feel like I have exhausted my options besides constant cleaning etc. Do any of you leaders have any advice for troubleshooting or suggestions of whom I could contact to inspect/repair this unit. I am using a Nagra X4S at 15ips with Stellavox AMI48 mixer. As always, any advice will be greatly appreciated. Thank you MarkC Quote Link to comment Share on other sites More sharing options...
Bash Posted March 23, 2018 Report Share Posted March 23, 2018 Norman Brown may well be your man. I believe he is a bit of a Dolby god. norbro@talk.com Quote Link to comment Share on other sites More sharing options...
MarkC Posted March 23, 2018 Author Report Share Posted March 23, 2018 Thanks Bash, I have emailed Norman, my fingers are crossed. Would love to get the unit back to spec. Cheers MarkC Quote Link to comment Share on other sites More sharing options...
