Magnum Dynalab MD-108 Brochure

In a world given to compromise, Magnum Dynalab has conceded nothing in its approach
to building their flagship tuner, the MD 108. Known for manufacturing FM Tuners of
unparalleled quality, famous for their balance of Sensitivity, Selectivity and Sonic
performance, it was only a matter of time before Magnum Dynalab achieved the pinnacle
of FM Tuner performance. Manfred Breunig, designer of Magnum Dynalab products, is
confident the MD 108 is that achievement.

Designed and constructed with the music lover in mind, the MD 108 is a hybrid tuner utilizing a truly
new ANALOG R.F. section with precise tube tuning and a separate audio stage
developed to exacting standards, utilizing two 12 AX 7 tubes in the audio switching stage.

Low Noise Dual gate MOSFETS Hand Matched Resonators
custom "Potted" Torroidal Transformer Auto Blend RF circuit

A precision tuning pot ensure optimum resolution from the five stage varactor front end. With three
ultra-sensitive bandwidth setting and enhanced selectivity, you are ensured the best possible signal
from any of the four antenna inputs (two analog, two digital), each selected from the front panel. An
exclusive muting circuit eliminates unwanted inter-station noise (auto blend circuit). To verify
performance, the MD 108 employs two accurately calibrated taut band analog meters to indicate
multipath and signal strength. In unison with these meters, a unique quad MATRIX EYE tube for
centre tuning means there is little guess work in optimizing FM reception. Low noise dual-gate
MOSFET transistors and hand matched resonators mated to double-sided, plated circuit boards
provide peak performance. The logic circuit which controls the tuner operation uses C-MOS
technology, which has very high noise immunity making external transients of little impact. The logic
circuit is controlled by gold plated momentary switches. With the switches always in a uniform
position, the MD 108 maintains a clean, aesthetically pleasing appearance.

Not to be outdone by the specially designed front end, a separate CLASS A audio stage was
designed. Using components and technology, worthy of the signal being received from the front end,
the audio stage, using two 12 AX 7 tubes in the final stage and a discrete amplification system is
designed to capture the ambiance of the music. The BALANCED circuit using a pair of bi-polar low
noise transistors are cross coupled to ensure a precise BALANCED signal to match your other higher
performance components. The Magnum Dynalab MD 108 establishes the new benchmark by which all
other tuners will be judged.
