Röhren Vollverstärker 2A3 von PureSound

The earliest audio amplifiers made
use of small, 3 element valves known as
directly heated triodes.
For many, the simple circuits that can
be built around such devices better
preserve the structure, colour and feeling
within the music than any other circuit topology.
One of the best sounding triodes, the 2A3,
is in production again and its characteristic
linearity has been employed in a novel configuration to create a particularly charming amplifier.
The Pure Sound 2A3 is an 18 Watt per channel
line level integrated design that allows for
the selection of up to 3 different source
components and control of the volume by
a high quality ALPS Blue Velvet potentiometer.

There are many amplifiers now making use
of directly heated triodes but few which
adequately address the particularly awkward
issues involved in driving these devices
properly. The Pure Sound 2A3 amplifier
features an unusual choke loaded driver stage
which allows the 6SN7 driver valves to
deliver the full measure of signal to
the push/pull output valves. This rather exotic configuration usually results in a
tremendous depth to the tone of
instruments and the Pure Sound 2A3
is no exception in this regard.

Very high quality components are used
throughout including selected carbon
film resistors and SCR polypropylene
capacitors. The power supply makes use of
twin valve rectifiers and choke smoothing.
The output can be configured for use
with 4 or 8 ohm loudspeakers.
The Pure Sound 2A3 may also be used
as a very high quality stereo power
amplifier if the volume control is
turned up fully.
