The AMC CVT3100MKII has been
designed to give superb sound quality
and represents outstanding value for
money.
The CVT3100MKII is a hybrid mosfet
valve design, capable of giving superb
sound reproduction. The components
are all of the highest quality.
The AMC proprietary designed Class A
hybrid MOS-FET amplification
topologies are accomplished as
following : a. Designed with 1000V
MOS-FET using exactly the same as
Classical Valve (MOS-FET Valve based
on majority current the same as
Classical Valve ) class A amplifications
in order to create excellent dynamic
range at the same time very accurate
and reliable with long life that Classical
Valve can't not achieve. b. MOS-FET
Valve Topology will be able to be
designed to more accurate in order to
have much better sound than Classical
Valve as FET Valve has much more
consistent and accurate characteristics.
c. MOS-FET Valve can keep the same
superb sound quality throughout the
much longer life. Classical Valve will
keep changing characteristic for worse
and worse sound reproduction through
the relative short life. d. The hybrid
MOS-FET Valve use output stage with
Classical Valve in order to make the
Class A amplifier lower cost for making
AMC
Class A amplifiers can be
affordable for all music lover to enjoy
instead of only for rich people. With
Classical Valve as output stage to take
high temperature without huge heatsink
in order to cost down. At the same time,
it will be ok for output stage to change
characteristics as output stage only
take care of power portion of Class A
amplifier. So, the topology can have
much lower cost and much longer life
for Classical Valve. e. So, AMC hybrid
MOS-FET valve design can achieve
superb sound quality, much longer life
time and with much lower price.
There are a few simple hints to follow in
order to get the best from your new
amplifier.
1) Do not stand any object or other
component on the top. Whilst the
CVT3100MKII is one of the coolest
running Class A valve amps available,
uninterrupted air flow is most important.
2) There are two silent fans in the base
under each pair of EL34 values. Again,
the air space under the amp must not be
restricted in any way. Never stand the
unit on a carpeted surface or anything
soft, or on another component which
generates heat.
3) The amplifier will sound best when it is
"warmed up," which can take 15 - 20
minutes.
Avoid operating the
PHONES/NORMAL/DIRECT switch
during this period.
4) The valves should last a very long
time but can be changed easily.
However, as there is always some
voltage present inside, even when the
unit is turned off, we recommend that
this is carried out by your AMC dealer. It
is only a five minute job for an engineer.
5) We recommend you retain the original
carton and packaging so that it can be
repacked correctly if it ever becomes
necessary to transport the unit or return
for service.
6) After switching off, always let the
amplifier cool down before turning on
again.
