Vintage Classic Stereo Tube FM Tuner

In very nice condition w/ beautiful original wood case!!!!!  Original box and packing are not included. Manual can be found on line.

The 10B, was built between 1965 and 1969 and was a classic from day one.


Without question the Model 10B was the most advanced instrument of its day. This is the Tuner that was rated by Hi/Fi Stereo Review
(December, 1965 issue) as " ... we have never seen a tuner to compare
with it ... so outstanding that it is literally in a class by itself."
Marantz engineers have bypassed the inherent limitations of conventional
circuits through the employment of bold new concepts and highly
sophisticated electronic techniques. The performance of every circuit
stage shows the dramatic order of improvement which can be achieved
through creative inventiveness. Now, with the introduction of the
Marantz 10B, all the requirements for real high fidelity reception have
been met. FM reception with the Model 10B, is comparable in every degree
with the clarity and fidelity normally found only in stereo tapes and
discs.

Performance properties of the 10B in regard to quieting, stereo
separation and distortion are without precedent. Its combination of high
sensitivity, ultra-sharp selectivity, fast quieting action and reduced
susceptibility to multi path effects, ensures exceptional results in
fringe area. While the advanced features and performance specifications
appeal to the primarily technically inclined, the Model10B's simplicity
of operation attracts the listener who is simply a lover of good music.
In whatever case, the extent of the new high standard established by
this fine instrument is recognized by all of critical judgement.



RF Section: The precision tuning capacitor has a
"Linear frequency" characteristic so that station calibrations appear
evenly and accurately spaced along a full 10" tuning dial. RF stages are
balanced-tuned throughout. An important feature is the radar-type,
balanced-bridge diode mixer.

IF Section: The unique Marantz IF circuit is based
on the development of an "18-pole" phase-linear. The ideal
characteristic of the filter pass band permit performance improvements
which are unobtainable with conventional coupled circuits.
Phase-linearity in the 200 kc pass band eliminates a major source of
high-frequency distortion and loss of separation 108 dB/octave cutoff
slopes make the Model 10B the most selective FM tuner in existence. The
strongest signals have no deteriorating effect on its ideal pass band
characteristics. IF alignment is permanent, being unaffected by tube
changes or normal aging.

Limiters and Discriminator:There are 9 limiters in
the Model 10B using matched pairs of silicon planar diodes. Each IF
stage is self-limiting, preventing overload on strong signals, and
eliminating the usual need for AGC circuits. Quieting on weak signals is
close to the theoretical threshold, with ultimate quieting well in
excess of 70 dB. The discriminator circuit is extremely linear, ensuring
low distortion through the sub channel range.



Multiplex: The highly sophisticated Marantz circuit
permits the inclusion of phase correction to maintain proper
phase-amplitude relationships. This allows the use of an extremely
effective SCA rejection filter without the usual loss of separation at
high frequencies. Separation is well in excess of 30 dB to 15 kc. The
output filter circuit provides very sharp attenuation of residual
sub-channel components above the audio range, eliminating noise and
interference from SCA. Precision-capped ferrite cup-cores or precision
toroidal coils are used for all filters. Automatic stereo switching and
inter-channel muting are both accomplished by means of ingenious
electronically triggered photo-electric circuits.

Multipath- Tuning Indicator: In March 1962, Marantz
introduced the concept of using an oscilloscope tube as a multi path and
tuning indicator in the early prototypes of the Model 10. As each
station is tuned, its correct center position on the pass band is clearly
displayed. Simultaneously, the presence of multi path becomes visible,
making it quite easy to readjust the antenna for best results. A panel
switch permits test display of the left and right FM channels, or
external signals from tape recorders, discs, etc.
