Picked this one up for a good Price. Nakamichi BX-300, Idler Tire version. Heads look fantastic, Pinch rollers average. It was advertised as a unit that plays for 5 minutes but then kept stopping after. Checked it out, replaced idler tire and to my horror the problem persisted. It came down to the reel motor having dead spots, it would not maintain torque at the playback take up speed. The motor in my BX-1 parts deck looked similar so I swapped it out, the problem disappeared. To do this, the direct drive motor board, capstans and capstan bearing plate needed to be removed just to access the last screw holding the reel motor mounting plate. A first for me, a good learning process and quite a few F-Bombs dropped during the process. 1 Swollen Capacitor had to be replaced, and a full recap is planned for the power supply once I get them ordered in.
Rest of the deck has been lubed and serviced, new capstan, back tension belt, idler. Capstan bearing and reel tables cleaned/lubed. Speed calibrated, Azimuth is perfect, no need to adjust after final tests.
This unit is a real cracker, dare I say it has a slight edge over my Gear Driven BX-300 model, but not by much. The sound is just incredible!
I do like the Idler tire version slightly better as the winding is very quiet, no whining of gears during Rewind/FF. The only catch is the tire has to be replaced every 5-10 years.
