Hi, I don't know if this should be here or in source with the reel to reel recorder....anyhow I rewired the tape recorder (yes I know it was really nice and new to me only about two weeks ago). The change was to make it possible to send the output from the tape play back heads to an external preamp...yup the one that was the subject of this thread. I can switch from internal preamps to external now.
This was a major improvement in an already good machine. The S/N is about 6 db better and the sound is every bit as good or perhaps even better than before. I used the high gain setting, NAB equalization and 47K input loading. Works great. A really worthy upgrade to most any recorder.
