GM
50: Integrated Amplifier,
50 watts £3,950
The new GM50 is a brand new integrated amplifier from the
valve specialists and the first in a new line of much
anticipated amplifiers. The GM50 features the build and
performance that were previously the mark of the company’s
top preamplifiers and power amplifiers. The look is pure
GRAAF – serious yet attractive. The amp sits behind a large
15mm aluminum panel with a transparent crystal window which
allows the listener a view of the functioning circuit and
glowing valves. LED indicators show through the window the
selected source for an added stylish nod to aesthetics!
Also a first for GRAAF and, unusually for a pure valve
amplifier, is the high quality remote control used for
volume, mute and input selection as well as power on/off.
The GM50 features six line inputs, two of which are
balanced and two tape outputs are provided. The internal
layout of the design is kept simple – an essential element
to result in superior sound quality. The overall design is
based around four KT88 valves working in push pull
operation for a gripping and full-bodied 50W of power.
These work in Class A-AB and each of the valves has its own
automatic bias control system for the best performance
whilst in operation.
The GM50 brings GRAAF’s renowned quality of valve sound and
technology to a new breed of integrated amplifier. It has a
full, impeccably detailed and powerful sound that will
deliver supreme performance with any genre of music.
Already the GM50 proves to be highly desirable product.

100 OTL power amplifier

The GM 100 is a fully-balanced power amplifier providing
100 Watts per channel. The output from its complement of
twelve PL-504 tubes is coupled to the loudspeakers via a TL
(transmission line) transformer, which allows a wide and
flat frequency response and the ability to drive virtually
any load. Dual-mono construction provides an excellent
three-dimensional sonic perspective, while the overall
sound quality is characterised by low distortion and a high
degree of transparency. Automatic regulation of tube bias
and offset gives fuss-free running. Weight 25.5 Kgs.
