no longer for sale

Very nice PAIR of AMERICAN made: Electra-Print 300B-DRD tube mono amplifiers with great TUBES & extras and options.

HIGHLY RECOMMENDED (see pictures)  !

Supplied with 3-Sophia 300B globe type tubes (one extra tube) as well as 2 pieces 6A3 tubes which can be used as an alternative and YOU can find which one best suit's your taste. Also 2-6AN4 tubes. 


"Our 300B DRD amp is derived from the classic Loften-White design. Using a 300B (or Sovtek 6A3) tube the output will be over 10 watts, -1dB 18 Hz to over 20 kHz, less than 1% distortion and only needing 0.7 V input to give full output. No coupling devices (capacitors or transformers) are used to minimize the coloring the sound. Power supply has been changed to give a efficient tighter more stable power delivery."

Improvements include:

  • Replacement of hard to find oil cap with large value electrolytic which increases coupling at low frequencies
  • Simpler means to adjust the operating points of both tubes
  • A means to measure current of output tube
  • Increased input sensitivity by 100%
  • Rectifier tubes eliminated, diodes giving increased tighter bass because of no 
  • forward voltage drop
  • Heat protection devices have been added where needed to safeguard Schottky diodes
