tbfan Posted February 21, 2021 Report Share Posted February 21, 2021 Hello, I'm new here and to be honest I don't know exactly where my topic belongs. I have had a Nagra III for 3 years (was my dream to have one). Now a week ago the belts started to give problems and I ordered new ones which will arrive next week. At the same time another error has crept in that I just can't find. When I record via microphone, the recording is crystal clear, but when I record via the two line inputs, the recording is simply muffled. Well, let's make it short: I'm looking for a service manual that says how to tune the Nagra (to a specific band for example LPR35 or LPR90). And a manual that says how to get the resistance and capacitor values to calibrate the Nagra. Nagra Audio provides the manuals (one is the user manual and the other is the service manual (it says how to calibrate but no values and the position of the parts is not really explained). https://www.nagraaudio.com/product/nagra-iii/ scroll down to downloads Quote Link to comment Share on other sites More sharing options...

SimonSays Posted June 4, 2022 Report Share Posted June 4, 2022 Any more info on both the Nagra III service manual (i have one in German but not English) and the source (preferably UK/Europe) for a rewind belt? thanks Quote Link to comment Share on other sites More sharing options...
