  • Notes
  • The Large Reel Adapter QGB is an accessory developed for Nagra self-contained monophonic, stereophonic and instrumentation recorders model E, 4.2, IV-S and IV-SJ. It permits the use of 10½" (267 mm) reels with cine-type reel holder and flanges with NAB or AEG-type hubs, which can hold 2400 ft (730 m) of 2 mil (50 µ) tape giving 1 hour of recording.

    This very sophisticated unit is fully automatic. The QGB ensures a stable tape speed and very fast forward and rewind functions, smaller reels can also be used with advantage. The reel supports accept interchangeable adapters fitting all existing types of hubs. These are coupled to the servo motors controlled by the tensiometers, maintaining the tape tension within very narrow limits.

    The QGB can be supplied from the internal batteries of the Nagra. The Nagra-QGB system can also be powered by an ATN-3 mains power supply (or equivalent) which connects to the "power" socket of the QGB.

    Each transistor/diode listed once per type.
