2011 Swart Atomic Space Tone Amplifier with Night Light Annenuator

The idea of the Swart Atomic Space Tone hit Michael Swart when he was working on a vintage Gibson Scout guitar amp. It had Reverb, Tremolo, and 15 watts of pure rocking vintage tone power but only three preamp tubes and two EL-84 output tubes. He thought to himself - I have never seen an amp that could do so much with so little and sound surprisingly good... but he knew it could be even better.

He knew something could be built revolving around  his favorite little tone generator, the 6V6.  He sent a note of thanks to his cohort for the inspiration for one of the best amplifiers he had ever built and the only thing he has found to equal the soul and amazing tone of the ST-6V6se but with even MORE power. He called it the ATOMIC SPACE TONE... and it's a winner - this beast sounds amazing!  This amp brings more tube soul than Michael thought possible, even compared to some of his favorite vintage amps. We are talking ALL TUBE circuitry, even the Tremolo and Reverb, all leading into the excellent 12" Mojotone BV-25m speaker!

The Atomic Space Tone is the 2nd amp in Swart's "Tweed Series" which takes a finger jointed pine cabinet and covers it with top quality tweed with the addition of a coat of lacquer to give it both durability and a classic appearance.  The sides are made of dark lacquered tweed giving the amp an instantly unique look.

This used amplifier is difficult to distinguish from new.  The Night Light attenuator is included, as well as the original footswitch.


  • The AC is cleaned and rectified by the reliable JJ 5AR4, this a very robust tube providing excellent sonics due to the total lack of solid-state circuits in the rectification stage (SS rectification leads to a more hard/harsh tone and slams the tubes on power-up causing excess tube wear).  A heavy duty, JJ 500V Surface mount capacitor is the mains filtering device.
  • Powered by Twin EH 6v6's putting out 18-22 cathode biased Watts; the twin 6V6s seem to really put out an amazing mixture of soul~tone.   (You can also sub 6L6s for a bit more headroom due to the extra beefy Heyboer Power Transformer.
  • A 12AX7 does duty as the driver and bias regulated Tremolo.
  • Reverb is all tube.  Tube Reverb is the only way to go and Swart's implementation leaves the competition sounding two-dimensional.
  • The first preamp tube is another dedicated rocking 12AX7 to drive this beast to Mount St. Helens and back.
  • Custom built, Heavy Duty, power and output transformers - HeyBoer USA - The New Leader
  • Carbon Comp Resistors for the BEST tone.
  • Mallory, Sprague and JJ Caps
  • Finest silver tinned cloth & Teflon covered wire
  • Hand Wired, point to point
  • Standby Switch - amp warmed up|extends tube life High and low inputs for high and low output pickups
  • Dedicated foot switch as well - Switch pedal included
  • 12" Mojotone British Vintage Series BV-25m
  • And a hand-made, finger jointed pine cabinet covered in light with dark tweed tweed side panels.  This cabinet is part of the magic of the Atomic Space Tone
