Otari MX-5050 MKIV-2 Service Manual
I have been searching high and low for a service manual for (or at very least, a schematic diagram of) the Otari MX-5050 MKIV-2 reel-to-reel tape recorder. I already have the "Operation and Maintenance Manual," but cannot seem to find the service manual.
I noticed that the operation manual is for two models: the MX-5050 MKIV-2 and the BIII-2. I do not, however, know whether these two models differ only in their enclosure or also in their electronics.
Any help, whether with the documents themselves, identifying similarities to another model that could serve as a point of reference, or simply pointing me in the direction of other resources is greatly appreciated.
