Specifications:
*Tape transport mechanism: 3 motor tape drive; 2 AC driven spooling motors; 1 AC driven capstan motor, electronically regulated
*Tape speeds: 3.75 ips and 7.5 ips, electronic change-over, tolerance from nominal +-0.2%
*Wow and flutter: (as per DIN 45507) At 3.75 ips <0.1%, at 7.5 ips <0.08%
*Tape slip: Maximum 0.2%
*Reel size: Up to 10.5” diameter (minimum hub diameter 2.36”). Tape tension switchable for small hub diameters
*Winding time: Approximately 135 seconds for 3,600 ft of tape
*Tape transport control: Integrated control logic with tape motion sensor provides
for any desired transition between different operating modes. Contactless electronic
switching of all motors. Remote control of all transport functions and electronic timer operation are possible

Huollettu juuri; Huollon on tehnyt TM:n ja Hifilehden testivoittaja-huollon ammattilainen; jarrut puhdistettu, säädetty. Rec-kytkin uusittu, piirikorttien liittimet puhdistettu, mittarivalot ja laskurin hammashihna uusittu. Äänitys säädetty nauhalle SM911. Puhdistus, voitelut, säädöt. Tarkastus, koekäyttö. Tarkka selvitys tehdyistä töistä dokumentoitu.
