Pen svart utgave i god stand.

Fisher Studio Standard Am/FM Stereo Synthesizer Tuner: covers AM and FM stereo, two IF bandwidths, automatic and manual tuning, digital frequency disyplay and LED signal strength meter, 6 memories.

this model turns out to have good performance and build quality. Call it the 'Studio Standard Sleeper.' The FM-2421 is equipped with a 4-gang varactor front end and wide/narrow IF bandwidths consisting of two or four CFs. The detector IC is an HA11225, the MPX IC an LA3380A and the AF amp an NJM4558. A few specs: Usable sensitivity, 9.8 dBf mono and 17.9 dBf stereo; 50 dB quieting @ 13.2 dBf mono and 35.9 dBf stereo; S/N is 75 dB mono and 70 dB stereo; alternate channel selectivity, narrow, is 70 dB; and THD stereo @ 65 dBf input is .1%, 1 kHz. A freshly aligned unit, tested for DXing, came up a little short of a Pioneer TX-9800 and a Hitachi FT-5500 MKII, and about equal to a Sansui TU-D99X. Those are all 5-gang tuners. Stock, the FM-2421 sounds good, with de-emphasis measuring at 70 µS. Modified with RFM's typical recipe, it sounds like all his other tuners. 8:-) The chassis is very solid and heavy with a massive power supply for a tuner. In fact, it has two shielded power transformers, one for main power and the second, unswitched, for memory backup. This tuner was available in either black or traditional Fisher champagne colors. It's of medium dimensions (3.5" tall), and has sensible ergonomics and a bright but no-nonsense dashboard.
