The CA-286 is a two-stage amplifier based on circuits used by Langevin, Collins, Gates, and Telefunken during the 1950s and 60s. It utilizes a unique Negative Feedback/Tone shaping circuit that allows the amp to be voiced from smooth, dark, and distant to very bright and forward.

The CA-70 is based on a two stage circuit designed by Western Electric in 1913. Between the 1930s and 50s, RCA, Gates, Langevin, and Western Electric all utilized this elegant and simple single ended design.

The CA-70S single channel utilizes the same two stage Western Electric circuit, as well as the same custom transformers and high end components as our larger PS6 modules.

After going through piles of vintage transformers, we set about finding the best winders in the country to deconstruct and faithfully recreate our favorite finds. All our designs are available enclosed in a modular/swappable octal enclosure, or raw with leads.
