The MD-108 serves as the reference tuner
for numerous audio reviewers and consumers alike. Simply put,
if you're considering the MD-108 you'll never have to worry about
looking elsewhere again. Magnum Dynalab has put everything
they know about tuners into this piece. It's 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 MAGIC
EYE tube tuning and a separate audio stage developed to exacting
standards, utilizing two 12 AX 7 tubes in the audio switching stage.
Advanced Features:
- Quad MATRIX EYE Tube Tuning
- Three Ultra-Sensitive Bandwidth Settings
- Low Noise Dual gate MOSFETS
- Custom "Potted" Torroidal Transformer
- Five Stage Tuning Front End
- Two Antenna Inputs
- Hand Matched Resonators
- 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.
