100W Class‑A Tribute Power for Serious Listening

The JCA100 Tribute is a limited-edition power amplifier built as a tribute to John Curl’s career. It combines refined high-end performance with robust musicality—designed for listeners who demand clarity, warmth, and disciplined power in one elegant package.

each monoblock runs pure Class‑A to 100 W into 8 Ω (with 200 W into 4 Ω on tap), and offers both balanced XLR and RCA inputs. You also get a 29 dB / 23 dB gain switch, heavy binding posts, and Normal/Low bias options (Normal = full 100 W Class‑A). Only 100 pairs are hand‑assembled in the U.S., with a portion of proceeds supporting John Curl and scholarship seedings for future repair techs. In short: serious artistry, serious power.
