Copland CTA-405 Brochure

Integrated Valve Amplifier

C TA 40 5

The COPLAND CTA405 is the result of careful research

and development, combining the best of classical
construction with the latest in circuit design.

The current capacity of the CTA405 power supply and
output transformers is fully sufficient for a 100 Watts output
power. However, with operation conditions set for minimum
variation of plate and screen current in the output stage,
excellent performance is obtained with very low feedback
at 2x 50 Watts per channel.

The output transformers are specially made for this
amplifier. Employing a high quality silicon ion core and
perfect symmetry of the segmented windings, a frequency
response from 5 Hz to 100 kHz is obtained with low
distortion and high stability over the entire audible
frequency range.

The system remote supplied will also control the Copland
CD players.
