One of Mr.Hyodo's
favourite KT66 based power amplifiers is the QUAD II, (The
QUAD II has recently been re-launched due to the demand from
audiophiles)
M Hyodo has now decided to design a new power
amplifier using the same KT66 tube but incorporating high-end
audio grade components, far superior to those used in the original
QUAD design.
TWO CHOICES OF OUTPUT TUBES: KT-66 AND OPTIONAL 6CA7 (EL34)
By
switching two selectors inside of the cabinet, you can use
either KT-66 or 6CA7 (EL34), a LED indicator at the
foot of each tube will change its colour and show you which
tube is in use. You also can use several other tubes of different
sound characterisic. (Refer to the Tube List)
STEREO/MONO SELECTOR SWITCH
You can
use CS-660P as a monaural power amplifier by changing the selector
switch giving an 80W output power.(40W x 2 when used as a stereo
power amp.)
A WIDE RANGE OF SPEAKER APPLICATION
Multi output
impedance selector: 4/6/8/16 ohms.
FLAT AND WIDE FREQUENCY
RESPONSE
A wide frequency response from 10Hz to 100KHz (-0dB)
caters for digital audio formats such as SACD/HDCD.
Other Features
- Twin-triode tube 6CS7 for the first-stage amplification.
- WBT
type speaker terminals.
- Large capacity choke-coil: 400mA
- Dumper tube 6CJ3 (for Colour TV use) is applied to delay
a supply of high voltage (B-Voltage) to output tubes in order
to protect output tubes from damage and to increase tube
life.
- All high-end audio grade electrical components (condensors,
resistors)
- Operation indicator lights up when the tubes are
warmed up.
- Wood Side-Panels
