Difference between McIntosh MR65 and MR65B

What arthur says plus: All the 65's say 'Stereophonic' front, and 'stereo' back. They were basically mono but had an output for an external multiplex adaptor. There was also an optional muiltiplex section available for them which you could order with the unit, or have installed later.

The 65B's all carry the "B" designation and are stereo units.

Jimmy, the 71 has that SDS? unit (almost worthless then and totally worthless now ;-) It's the smaller square black can and was for tuning private/subscriber Muzak-type programming that some regular broadcasters attached to their primary signal. Also the 65B and 71 have 4-gang tuning condensers. All the others have 3-gang. (I have two 65B's also, but I think I'm going to sell one of them ;-)

Did you know Aaron Russo was Bette Midler's original manager/producer (gosh I wish I could get that sort of data out of my head!!) Yeah, for this country to finally realize it's promise, the illegal Fed. Res. and the illegal IRS will both have to go. In the meantime ;-) I have a Technics ST9030 I'm going to sell soon as well (8-gang tuning condenser!!) so that's my Japanese tuner for now ;-)
