Tandberg 3001

Factory literature on the Tandberg 3001 is thin, but period reviews give a clear picture of a serious FM tuner. It is also called the TPT 3001A. It belonged to Tandberg's 3000 series of separates, along with the TIA 3012 integrated amplifier and the TPA 3003 power amplifier, shown at launch around 1980 (Modern Recording, June 1980, p.31). Audio (March 1988, p.51) spent six months with the 3001A and didn't want to send it back. The reviewer called himself an "FM tuner addict" and found the Tandberg genuinely outstanding. His only complaint was that it made his test gear seem inadequate.

The 3001 pairs a smooth analog dial pointer with a digital approach to stability. The reviewer admitted he still liked watching a pointer glide across a calibrated scale. A custom 98 MHz crystal oscillator, made by Tandberg, keeps the local oscillator rock-solid (HiFI-Stereo, March 1981, p.54). That same review noted that the FM noise floors were so low that commercial lab generators couldn't measure them, so Tandberg had to invent its own test procedures. In preset mode a channel-center meter doubles as a rough frequency readout, spanning 88 to 108 MHz. An "AF" light goes out when the station is properly locked.

Audio (November 1983, p.83) described a visit to Tandberg's Norwegian factory, where prototypes of the 3000 series were shown. The writer found them painstakingly engineered, with each detail considered. By 1988 the 3001A was still being reviewed and praised for showing what FM could do when fed good signals and careful antenna placement.
