Realistic (Audio Power Meter) APM-200 Model 42-2102 User Guide
Just obtained one of these. I suppose a user guide isn't essential, but seems like it might have information that a novice (like myself) might be interested in or need knowledge of before messing up the day. Anyone got a clue as to where to get one of these guides/manuals or if they even came with one? Apparently was offered (the APM-200 unit) in 1980 for $49.95.
