Would-be filter modders are cautioned that while replacing a tuner's stock filters with new narrower ones will certainly improve selectivity, if the new filters have not been professionally measured and matched, there is likely to be a noticeable degradation of audio quality.
Particularly when changing filters in a digitally tuned receiver, one should ensure that the new narrow filters are centered right on An alignment can improve a tuner's weak-signal reception, distortion, and stereo separation.
Also, in many cases the tuning dial reads incorrectly, and an alignment solves that problem although it should be pointed out that a well-calibrated tuning dial does not necessarily indicate that the tuner is properly aligned. Setting the tuner's detector correctly can also improve reception of adjacent-channel stations. If one listens primarily to strong local stations, it may not be apparent that a tuner is out of alignment, and a misaligned tuner can have sensitivity as high poor as uV and still sound fine on locals.
With a good alignment, the sensitivity of many top tuners can be improved to 1. Then a bunch of BNC cables, test leads, probes, etc. In some cases, you may have to build adapters or probes from scratch or otherwise improvise. Procuring the equipment is one thing, and figuring out how to use it successfully is another.
Many people could do it with proper training and help, but it is best learned by observing in person, like learning a trade, rather than by reading how to do it. Usually the manual for the stereo generator is a good starting point. Our panelist Bob discusses alignment techniques in our FMtuners group in the series of posts beginning here , and here is a useful discussion of alignments of Scott tuners, most of which have broader application. When selecting a shop for tuner modifications, repairs, or even just a tuneup, ask what kind of test gear they use to complete the final RF checkout and alignment.
We believe it is critical that RF mods, repairs, and alignments be fully measured to ensure that the tuner meets or exceeds factory specs as set forth in the service manual. This critical measurement should be in addition to the final listening test.
