The life with FM is great – did not play record for a month or so… I was playing with some other tuners that came across Kenwood L-02T and Mono Scott 310. Both were no good.

Anyhow, the experimental Sansui was running all that time. The “tone” at HF got burned and caught on but the low end never was as good as on my original tuner. I returned all “parts upgrade” that I did but it did not help. So, was about to let this tuner go but today I decided to give to the experimental Sansui one more chance. Do not ask me HOW is found it but after 3 hour of trying I did found that the problem was the faulty C605 capacitor. After I replaced it the experimental Sansui was singing very-very nice. I put all parts back and even more. I found a very cool way to push it slightly further: I bypass the out 5uF caps (C17, C19, and C15). The tuner has IC in out stage and the blocking caps block DC from the IC. I measured the DC as it was 480mV. I figured: so what?

I tried and I heard no clicks – no surprise: I greatly attenuate the signal in my preamp to run my system. So, I was running Sansui DC-coupled with no caps after output state. Great improvement in upper range – love it! I will probably convert my original unit to the same tweak.
