Knasty; I see from an earlier post that you have a 'user's manual' for an Advent 100A Noise Reduction Dolby Unit. I see you had scanned the service data for this unit, have you by chance made the user's manual available in pdf or some other format? I am having trouble getting my 100A running correctly and would like to get a copy of the user's manual. Can you help me? NevadaM
