About the Super 2A3 SET
The Super 2A3 SET is a dual-chassis vacuum tube amplifier featuring a 6SL7 input stage DC-coupled to a 6SN7 cathode follower driver stage. It employs twin 5U4GB tube rectifiers, Transcendar output transformers with 4/8Ω taps, and independent DC power supplies for 2A3 filaments. The design prioritizes signal purity through film capacitors, toroidal transformers, and minimal negative feedback.
