Had a 75A-3 years ago as a novice along with a crapped out 32V-1 the 75A-3 was deaf along with some problem in the PTO from what I remember. One thing I don't like with the 348 is not being able to adjust AF, and RF gain independently. By the time the RF gain is turned down enough to limit distortion on SSB AF gain becomes low as well I know SSB wasn't around back then only AM, but I still may experiment with separating the controls. Have to admit the R388 is a much nicer looking receiver IMO. and probably much easier to work on as well.
