Atomic Jr
The ST-6V6se circuit plus a dedicated triode spring reverb stage, still just 14 lbs, in a tweed cab with dark side panels.
About this amp
Space Tone Atomic Jr starts from the ST-6V6se’s 5-watt Class A single-ended heart and adds a 12DW7-driven triode reverb stage into a spring tank. A switchable gain option stands in for the 6V6se’s feedback switch, and the amp remains cathode-biased and hand-wired point to point in Swart’s signature finger-jointed pine cabinet.
