For sale is a silver Tandberg 3001 programmable FM tuner in perfect working order with some minor cosmetic blemishes (see photos). Our technician has installed a new battery, new selector switch kit, and the unit has been fully serviced. Comes with power cord and FM antenna.
Description from Hifi-classic.com:
"The 3001 tuner does not employ digital synthesis, or even a digital frequency display, because the required pulse circuitry inevitably increases the tuner's noise level to some degree. One of Tandberg's goals was the best possible signal-to-noise ratio both in mono and stereo reception, and the success of their engineering efforts can be appreciated from the tuner's S/N rating of 95 dB in mono and 82 dB in stereo at the usual 65-dBf signal level (the stereo S/N rating improves to 92 dB at 85 dBf input) These S/N ratings are 10 to 20 dB better than those of most top-quality tuners and are well beyond the capabilities of the Sound Technology 1000A signal generator (used by us and most manufacturers and test laboratories) or any other presently available signal generator that we know of.
Since commercial laboratory signal generators are not able to measure these low FM noise levels, Tandberg had to devise special measurement techniques for that purpose.
Physically, the Tandberg 3001 is a "low-profile" unit only 3-1/4 inches high, 17-3/8 inches wide, and 13-3/4 inches deep. It weighs just over 15 pounds. The silver-colored front panel appears quite conventional, with a fairly short dial scale calibrated linearly across the FM band (the tuner does not have AM coverage) and a flywheel tuning mechanism operated by a large knob. To the left of the dial are two meters; one is a channel-center tuning indicator and the other reads signal strength directly in microvolts at the tuner's 75-ohm antenna input (it does not have the usual 300-ohm antenna circuit). The microvolt calibrations are logarithmic, covering a range of 1 to 1,000 microvolts (μV). The meter has an auto-ranging feature so that when the input exceeds 1,000 μV its scale expands by 1,000 times to cover a range of 1,000 μV to 1 volt; a red LED comes on below the meter to indicate that fact. Next to the meter is a small window marked program, which will be described shortly.
The lower portion of the panel contains small knobs for i.f. bandwidth selection (wide, normal, narrow) and a continuous muting level adjustment calibrated logarithmically from 1 to 3,000 μV. Four small pushbuttons with red LED lights above them control muting, servo (an AFC system that is automatically disabled whenever the tuning knob is touched and comes on when it is released), ANC (an automatic noise-canceling circuit that operates below certain signal levels), and mono operation. There is also an mpx stereo-indicator light.
To the left of the program window are eight small pushbuttons for the preset tuning channels, and below them is a store program button. Up to eight frequencies can be stored in the tuner's memory by simultaneously holding in a numbered button and the store program button. Large red numbers appear in the program window to show which button is in use, and an "F" appears there when the tuner is in its manual tuning mode. In preset operation the channel-center meter becomes a rough indicator of the tuned frequency, reading on a second scale from 88 to 108 MHz; a "AF" light below the meter goes out to indicate that it no longer shows channel-center tuning. Touching the tuning knob at any time restores manual operation and disables the AFC. The remaining front-panel controls are for output level and power.
On the rear apron of the 3001 tuner there are both fixed- and variable-level audio output jacks, oscilloscope outputs for external multipath indication, a detector output ahead of the de-emphasis, and a three-position de-emphasis switch offering 25-, 50-, and 75-microsecond characteristics. The tuner has a detachable a.c. line cord and a switch to select either 115- or 230-volt operation. The only antenna input is a coaxial connector for a standard 75-ohm cable fitting, since Tandberg feels that the full performance of the tuner is likely to be realized only with a high-quality antenna having a shielded coaxial (75-ohm) feed line."
