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.

Copland CTA405
Copland products are a true favourite at Oxford Audio and when the NEW Copland CTA405 was launched we were very excited! For those that loved the legendary 501 model, just wait until you hear the 405. It takes the 501 several steps further!
If you are in the market for a new valve integrated, make sure the 405 is at the top of your auditioning list.
Amplifier details follow....
Intro
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.
