I want to sell my TU-X1. It is a legendary tuner and you can find all about it at http://fmtunerinfo.com/sansui.html#sansui-tux1.
My tuner is recently back from Joseph Chow's shop, Audio Horizons/Components Plus, where it received a comprehensive set of upgrades and alignment to both the AM and FM sections in May, 2012. This service cost $775 plus shipping, and was well worth it. The tuner gets lots of stations with my rooftop FM antenna and a 100-foot straight wire outdoor AM antenna. It sounds superb. However, I just have too many tuners. My much more heavily-modded TU-9900 will meet my needs, and so I am going to part with this one.
I realize that $3375 is a lot of money, but this is a lot of tuner. You can sometimes get one on ebay for $2500 or a little more, but this one is properly sorted out, at considerable extra cost to me, and not just an old ebay tuner.
The tuner is in fine condition, with but one spot on the case top (not the front panel), about 1/8 inch x 1/4 inch, where the black paint is worn off. I replaced the original hard plastic feet with sorbothane half-spheres. All features and functions work properly, all lights work, etc. Part of the Chow mod included bypassing the front-panel volume controls as they are unnecessary and could degrade fidelity.
Here is the list of modifications performed by Components Plus:
1. Install Furutech Gold IEC Socket
2. Hot wiring between IEC socket, power switch, and fuse holder with Cardas chassis wire
3. Replace signal wire from FM output devices to output RCA jacks with New Horizons interconnect wire.
4. Replace rectifier diodes with high speed soft recovery low noise diodes and remove rectifier bypass caps
5. Replace 8 mylar coupling caps with polyproylene caps
6. Replace 19 electrolytic caps with Blackgate or Panasonic FM caps
7. Reconfigure the antenna internal wiring to a true 75-ohm impedance and removing the balun, improving FM sensitivity
8. Replace 2 ppairs of output RCA jacks with Audionote silver machined jacks
9. Complete alignment, both AM & FM sections - sensitivity, THD, separation, 19kHz leakage, meter & dial calibration
10. Clean up all dust throughout, rinsed & lubricated - looks and smells like brand new inside.
11. Replaced 4 electrolytics in AM section with polyproylene caps
12. Replace signal wire from AM output devices to output jacks with New Horizons interconnect wire
13. Bypass front panel volume pots - they were unneeded and can adversely affect sound quality.
