Products CA-906 Two Chassis Preamplifier

CA-906 Stereo Preamplifier
The CA-906 stereo preamplifier employs an advanced circuitry and high quality components to provide outstanding musical reproduction of your favorite music. It also features an external power supply (CA-906P) in a separate chassis to avoid undesirable electro-magnetic interference with the line stage.

Like our other products, the CA-906 is engineered and built to provide a lifetime of musical enjoyment. The circuitry components used in the CA-906 are carefully chosen and hand soldered on the military grade epoxy circuit boards. Even the DC power cable used to connect the line stage with the power supply was hand built by our engineers to meet our standard.

The power supply utilizing four selected vacuum tubes (1 x GZ34, 1 x 6SL7 and 2 x 6V6) incorporated with a newly design circuit. The oversize power transformer is custom wound and two chokes are also used.

The line stage utilizing four military grade 6SN7 vacuum tubes. Two custom made chokes are also used in the line stage. Circuit highlights include the use of a total of eight pieces custom made Canary capacitors.
