I have a two Nakamichi BX-125 decks, two BX-300's, CR-5A & CR-7A and taped mega amounts in the 80's & 90's. Mostly, if not all, Grateful Dead bootlegs.
The BX-125's were my slave decks for sharing the music. Man, I would make about 20-30 copies a week for people and never ONCE had problems with any of them.
Sadly and happily, I am a FLAC guy now and my 2000+ Dead tapes sit quietly in a closet.
Loved my NAK's
