这是国外著名FM媒体fmtunerinfo对根德机器的评价:
Grundig search eBay
Please post in our FMtuners group if you have any information about any Grundig tuner. The top U.S. model in Grundig's Fine Arts line was the very rare T9000 (1988, $1,200), which we've seen on eBay only twice in four years ($211 in 1/05 and $150 in 3/06). Lower in the line, the still-rare T-903 (1988, $450) sold for $100 in 12/02 and $56 in 3/03 on eBay.
Grundig T 7500 (1983?) search eBay
The T 7500 replaced the older ST 6000 (30 presets, battery backup) and retailed for approximately 800 DM in Germany (about $300 US). It is not known whether it was ever sold in the U.S. Our contributor Stephan reports that it has three tuned front-end circuits (one before the preamp, two after) and an additional two in the LO, making it equivalent to a typical 4-gang tuner. There are four cascaded FM IF filters, sufficient for very good separation at 300 kHz and halfway decent separation at 200 kHz. The PLL demodulator uses a Philips TDA1576 chip (another of those is used for scan tuning and on-frequency recognition), and after a discrete birdie filter a TDA1578 serves as MPX. The AF amp consists of discrete transistors, and coupling caps are 1u before and 47u after. Features include 15 presets that also store a 4-character alphanumeric note along with the mono and muting settings, if applicable, 25 kHz tuning steps on FM (with display to 10 kHz), a roughly logarithmic 8-LED signal strength meter, and adjustable output volume and scanning thresholds. Magazine reviewers liked its combination of good reception and sound with useful features at an excellent price point (it was compared to a Revox costing almost three times as much, possible a B261, and fared very well). Overall, Stephan calls the T 7500 "a tuner done right." There are some areas where cost-cutting shows, however, including only one IF bandwidth and no switchable attenuator. In a comparison with the Onkyo T-4650 (Euro version of the T-4500), Stephan found that the Onkyo is more selective in Narrow mode but the Grundig sounds better (somewhat warmer and with slightly better highs), and is somewhat more sensitive in mono. "Stereo sensitivity differs from the Onkyo insofar that the stereo decoder seems to apply some kind of blending when the signal level diminishes, until you get to the point where stereo is still being displayed but is no longer actually decoded." There is a also a Grundig ST 6500, virtually identical to the T 7500 but with a somewhat different case. |
