The CA-70 preamplifier module is designed as a tribute to the iconic American two-stage circuit originally developed by Western Electric™ in 1913 and produced by various manufacturers, including RCA™, Gates™, and Langevin™, from the 1930s to the 1950s. Renowned for its rich, thick tone, this vintage octal tube circuit is widely regarded as the epitome of the classic "old tube preamp" sound.
The CA-70 PS6 preamp module features Coil Audio’s proprietary transformers, high-quality capacitors, resistors, and NOS octal tubes. It operates seamlessly with the PS6 Rack Tray and Power Supply for optimal performance.
