Bpaulovich --- Good point you make of coming to conclusions with tuners having questionable alignments and having only one sample of a tuner on hand for evaluation. This often accounts for wrong conclusions. I just finished two TU-X1s: alignment, IEC jack, lamps. One also had a problem in the first RF stage, the second one was more sensitive but the AM had some problems. Of three recent TU-9900s, only one was a killer. The best audio I have obtained from a Sansui is from a modified TU-417 and similar TU 317. The bass is so good and extended that air conditioning rumble on many classical programs can be heard. This does not happen often on any tuner. One owner tossed in the towel on his MR-80 in favor of the much cheaper TU-317. Also, the TU-417 and TU-317 need an additional IF filter to snuff up selectivity.
