• Anotaciones

• Four-track stereo / mono, 3 speeds: 7.5 inch/sec (19cm/sec) @ 30-20000 Hz, 3.75 inch/sec (9.5 cm/sec) @ 30-14000 Hz, 1.875 inch/sec (4.75 cm/sec) @ 50-7000 Hz. Channel separation better than 60 dB.  4 separate tape heads: erasing head, recording head, playback head, and bias head.  Synchronous motor. 3 channel output, left, right and center (monoaural).

  The "X" in "64X" stood for "Cross Field Head." It was an extra head that fed a bias signal from behind the tape across to the opposite channel record head. The cross field head system is intended to give lower distortion during recording. It doesn't affect playback, so it has no effect when playing pre-recorded tapes or tapes recorded on another machine.

  This hybrid set used 10 tubes, 8 transistors, and 2 selenium rectifiers.

  U.S. Version for 60 Hz, 115V has an Interlock system for mains input.
  See the schematic for other differences (motors, transformer) regarding the mains frequency and voltages.
