Revox B760 Tuner

Here we have a classic vintage tuner from Swiss company Revox. Although cosmeticallyin pretty poor condition it seems to be working fully and capable of surprisingly good sound quality with a dedicated aerial. It will be suitably packaged and comes with manual, mains cable and our normal three month warranty.
Revox Said….
As easy to use as a touch-button telephone, the Revox B760 FM tuner brings all the music on the air to your fingertips. Every station, weak or strong, is locked in with quartz-crystal accuracy for crystal-clear, undistorted reception.
With so many stations on the air, particularly in crowded metropolitan areas, it’s sometimes hard to know whether you’ve tuned into the station you were looking for. With the digital readout of the B760, on the other hand, you always know the exact frequency to which you are tuned, correct to two decimal places. Thus, if the desired station has an assigned frequency (which is always crystal controlled) of 101.3, just turn the tuning knob to that frequency on the display and the ”frequency computer” in the B760 will automatically lock onto the station.
Because the digital synthesizer in the B760 is also crystal-controlled, tuning is far more accurate than could be achieved by hand. Further, there is no need for AFC circuits which can fail to lock onto a distant station, and which add harmonic distortion.
The B760 even contains a sophisticated 15-station electronic CMOS memory, eliminating the need to retune among your favourite stations. Any desired station can be stored in any of the 15 locations, and thereafter, to receive the station, you need merely press the assigned button.
The sophisticated circuitry can accommodate even the weakest signals, whose correct tuning and relative strength are shown on the wide-range meters. The signal strength meter is particularly useful in accurately orienting an antenna for best reception.
And the annoying swishing, hiss and pops between stations are eliminated by an effective muting circuit. Only if a signal meets your desired listening criteria will it be received, and the switching threshold is adjustable over a wide range with separate controls for monaural and stereophonic broadcasts.
The Revox B76O is designed to receive all internationally-assigned FM channels, from 87.00 to 107.975 MHz . While the spacing between FM stations in the U.S. is currently a rather wide 200 kHz, in foreign countries it is often only 100 kHz, and sometimes less. The normal B76O tuning increments of 50 kHz provide for both situations, as well as for the fact that stations abroad are sometimes allocated frequencies that cannot be received by many digitally-controlled tuners. To
ensure worldwide usability under the most congested FM channel allocations, a button on the B760 is provided that permits tuning increments of only 25 kHz. This feature may also be needed with certain community antenna systems.
Even with a “centre tune” meter it is impossible to set a conventional (analogue) tuner to the exact frequency of the broadcast station, yet ultra­precise tuning is necessary to achieve minimum distortion. The digital tuning system of the Revox B76O, however, automatically ensures that each station received will be tuned to quartz crystal accuracy (±0.005%), just as is the transmitter.
Up to 15 of your favourite stations can be assigned to its own automatic recall button in the Revox B760. The specific frequency of the station selected for each of the memory-recall positions is “remembered” in the CMOS digital logic circuit so that tuning is as exact when using the memory feature as it is when tuning manually. Should station preferences change, new selections may be substituted for previously assigned memory buttons, and on emergency, battery-operated power supply (located in a protective troy within the B760) keeps the memory selections active even in the event of a power failure.
A sophisticated muting circuit is included in the B760 to prevent the usual whistles and swishing sounds that occur when shifting from one station to another. If it is desired to listen to on exceptionally weak (noisy) station that would normally be suppressed by the muting circuitry, a switch is provided to disable the automatic muting.
Stereo and monophonic broadcasts require different signal strengths for quiet reception, and for different purposes different criteria for acceptable signal quality ore appropriate. For this reason, the B760 contains separate monophonic and stereophonic threshold controls that permit the user to select precisely how strong a station’s signal must be in order to be received rather than being muted out as “noise”.
Since stereo broadcasts require ten times as much signal voltage at the antenna terminals as do monophonic transmissions, background hiss is much more frequently a problem in stereo FM reception. One solution with a weak stereo signal is simply to switch the tuner to its monaural mode, yet often this is a more drastic remedy than is really required. The Revox B760 therefore contains a switch that reduces but does not entirely eliminate stereo channel separation by partially blending the high-frequency (hiss causing) signals together, making it possible to enjoy stereo reception even of marginally-weak stations.
So you can listen to your tuner in privacy, the Revox B760 has a built-in headphone amplifier with its own, separately adjustable level control.
