Don's List Lab

This page is intended as a place to put simple lists of tuners that have one particular feature or another. We'll need input from readers to make the lists as comprehensive as possible. Please post additions to existing lists, or suggestions for new lists, in our FMtuners group. Tuners don't have to have TIC writeups in order to be listed here. We've renamed the page in honor of our contributor Don W., the most prolific creator of list topics.

MPX Decoder ICs

Don writes, "I have always wanted to see a list of tuners which have certain MPX decoder ICs. The 'big 3' I would like to see are the LA3450 and LM4500 (because of their unique decode waveforms), and the HA11223 (near universal praise as capable of excellent sound). I have compiled my own list, but I can't be sure it's completely correct. There was a discussion of this topic in FMtuners." If you can give us a hand and help us improve this list, let us know.

Tuners with Sanyo LA3450:

*Our contributor Esmond says the Quad FM4 uses the Philips TCA4500, which appears to be identical to the LM4500. He believes that later Quad tuners also use it.

Our contributor Paul Baptista says the Arcam Delta 80 and Telefunken RT200 (whatever those are) use the TCA4500A, the Motorola and Siemens part number for the LM4500A.

Tuners with three or more IF bandwidths

Here's another good list suggestion from Don. The benefits of having wide and narrow IF bandwidths in a tuner are fairly basic: wider filters tend to produce the best audio quality, while narrower filters improve rejection of adjacent-channel interference. Three bandwidth settings, with intelligently chosen filters, can provide even greater flexibility for audiophiles and DXers alike. Only the T-85, to our knowledge, has four IF bandwidths.

Tuners that have MPX implemented using discrete transistors (solid state) instead of an integrated circuit

Thanks to our contributor Paul for the idea. There should be other tuners in this list, but here are a few to start with:

Kenwood 600T
Kenwood KT-7000 and KT-7001
Kenwood KT-8005 and KT-8007
Kenwood KT-8300
Sansui TU-9900
Tandberg 3001 and 3001A
Yamaha CT-7000
Yamaha T-70 and T-80(?)

Don notes: "Here's the tricky part: Some tuner designs have a MPX chip that is used to generate a 38 kHz clock locked to the 19 kHz pilot tone. The actual MPX decoding is then done by external circuitry. (At least that is my understanding.) My impression is that the T-70 falls into this category. Bob says: 'The KT-8007 uses an outboard MPX switching scheme very similar to the KT-8300. If working correctly, you should see 38 kHz square waves coming out of pins 4 and 5 when a 19 kHz pilot is present on the input.' I take this to mean that both these Kenwoods do the MPX decoding in discrete circuitry outside of the MPX chip."

Our panelist Bob confirms: "That's right, you can have:
1) Fully discrete, no chips - older tube and solid-state tuners, mostly designed before 1975
2) Hybrid - MPX chip with outboard switching
3) Dedicated single MPX chip does all decoding - most solid-state tuners
4) MPX decoding using multiple chips and or discrete components together in an advanced modern design, in many (but not all) cases using pure sine wave decoding

In category 2 are many high-end tuners, including the KT-8007, KT-8300, 600T, TU-9900, T-70, and I think the Yamaha T-80 also. In category 4 you have the Yamaha T-85 and TX-1000/2000, Rotel RHT-10, most high-end digital Pioneers like the F-9, F-90 and F-99X, the Sansui TU-D99X, and most top-model digital Kenwoods."
