I'm interested in buying an Auto Reverse Cassette Deck. Specifically, an Akai GXR-66 for $200 at J&R. It has b&C dbx gx heads and a couple other nice features and originally retailed for about 420. The question I had is that I had heard that auto reverse decks don't track as well. Is this only true on the B side? IS this only true with tapes not recorded on the deck? Does not using this feature i.e actually taking the tape out during recording and/or playback stop this problem or is it still present? If anyone has any other comments on this deck (or others) they would be appreciated.

Stealing a piece of Vintage 8-TRACK technology it actually uses a solonoid to move the heads back and forth. Lately, mine has taken to drifting into middle positions and playing both tracks at the same time. -Ron

The basic priciple behind most all auto-reverse decks (the only ones that I can think of that don't use this principle are the Nakamichi RX series) is that the playback/record head is mounted on a turntable. When you ( or the deck ) reverse, the head is spun on this table. The only problem with this is that the stops wear out, something gets in between the stop and the table, or some other such thing, and causes misallignment. Nakamichi corrects this with their auto-asmizuth (is that right? I don't know) allignment technique. This alligns the head every time for "perfect playback." Hope that I haven't made a mess of things too bad. -- Butch Anton University of Chicago uucp: ..!ihnp4!gargoyle!sphinx!ant3 mailnet: x9.xba@UChicago.Mailnet bitnet: ant3%sphinx@UChicago.Bitnet ARPA: x9.xba%UChicago.Mailnet@MIT-Multics.ARPA USnail: 2560 E. 72nd Place (312) 731-6314 home Chicago, IL 60649 (312) 731-6750 work

I'll keep looking for that turntable in my walkman, too, and if I ever find one, I'll let you know...no, I'll let you have it. -- ------------------------------------------------------------------------------- David Hsu Across the net...
