Super 300B SET Monoblocks

About the Super 300B SET Monoblocks

The Aric Audio Super 300B SET Monoblocks are premium hand-crafted vacuum tube amplifiers featuring a 6SN7 input stage in SRPP mode, 6V6 driver stage in triode-strapped mode, and 300B single-ended output stage. They include a fully outboard power supply with twin 5U4GB rectifiers, dual OA3 regulators, 3 chokes, and 100% film capacitors for each filter stage. Interstage transformer coupling eliminates typical 300B wooliness, providing extended frequency response and dynamics sounding like 15 watts. Key components: silver-coated copper USA-made Transcendar output and interstage transformers, Jupiter copper foil paper-in-oil coupling caps, copper wire signal path, copper shielding, Vishay resistors, Schottky diodes, DC filaments, gold-plated sockets/jacks, and hand-built walnut chassis. 100% point-to-point wired, pure analog design with no chips or active regulators. Includes Linlai 300B (x2), NOS 6V6 (x2), NOS Hytron 6SN7 (x2), (2) RCA 5U4GB, (2) NOS OA3 regulators, custom power umbilical cables (x2). Build time 3-4 weeks, 2-year warranty. Optional upgrades: Tier 1 Duelund CAST silver/copper hybrid capacitors (+ ), Tier 2 adds Takman resistors and Jupiter Cosmos cathode caps (+ total).
