Traynor YBA1 Bass Master from 1978, with new tubes, modified for high gain. All tube, except for the solid-state rectifier. High input accesses all four preamp gain stages. Low input bypasses one preamp gain stage. Three-position bright switch and Voicing knob (to shape the low end) added to front panel (in place of the bright inputs), and an IEC power input receptacle and Depth knob (with push/pull switch for NFB/feel) have been added to the rear panel.

There are a few blemishes to the cab, especially on the removable top panel to which the handle is secured (see photos). The electronics are in very good condition (stock components) to excellent condition (new stuff).

Additional tech stuff:

  • new, Apex-matched 2xEL34 (EH)
  • new 4x12AX7 (3 JJ; 1 Tung Sol)
  • 12Vdc power supply added for preamp heaters (V1 and V2)
  • choke added
  • preamp tube socket added
  • fixed bias adjustment added
  • long-life filter caps added
