CTA405

Integrated amplifier





Production start: 2005 / Ended: 2019


The CTA405 is an integrated valve amplifier with five line-level inputs, including a tape monitor loop, and a built in RIAA phono circuit accommodating moving magnet and high output moving coil cartridges. Rated at 50 watts per channel using the legendary 6550 beam power tubes in ultra linier configuration excellent performance is obtained with low global feedback. A complete line stage similar to the one found in the Copland CTA305 pre-amplifier is installed directly behind the input terminals, providing a low output impedance buffer between the amplifier interconnect cables and the level control prior to the power amplifier section.
