Following the positive response to our flagship L300 pre-amplifier, puresound
has developed the L10, a new, more affordable
design which incorporates much of the thinking that makes the L300 so
highly
regarded. The L10 has 4 inputs, a separate
passive Record In Record Out loop and two pairs of single ended outputs.
The circuit
uses output transformers and a sophisticated
full valve rectified, twin choke smoothed power supply. It also offers
remote
control of the volume via a separate handset. In the L10, source selection is via a high
quality switch located near to the input sockets. The chosen source is
routed to a
high quality motorized, film potentiometer
and from there on to the audio circuit. This consists of a
single
ended triode stage loaded by a custom wound
wideband output transformer which steps down the amplified signal
allowing it
to be coupled to the power amplifier at a
manageable level and as a low impedance source. The output stage of the
L10 is impervious
to long interconnecting cables or lower
impedance power amplifier input stages.
The
L10 also incorporates an extremely sophisticated power supply
to maintain constant operating conditions for
the audio circuitry. It includes a valve rectifier, and a twin choke
filtered
LCLC stage which provides a stiff, voltage
rail allowing the audio circuit to operate in a calm and orderly way
regardless
of the demands the music makes on the
amplifying stage. Filament supplies are fully regulated to further
reduce the potential
for noise.
