I looked for a Sansui SE-99 equalizer for a long time and finally got one off epay as a Christmas present.
The seller listed it as "used" i.e. in apparently working condition. However, upon powering up if beeped and one of two EQ displays lit on only partially and didn't display the expected array of horizontal bars in the middle. Turned it off and on again; same thing. Only at the third time both displays lit the same way as in picture listed in epay auction i.e. array of horizontal bars at the middle. Those bars moved dependent of the music input signal although not to the full scale and in a kind of anemic way.
I used it for 10 minutes or so, then powered it off. Powered back on right away and the problem returned as described above then powered off and on again with the same result.
Thus, the Sansui's displays lit properly only upon powering on and off 2-3 times, not straight up. I got the user manual from the Web and it says nothing about this.
What this could mean? The SE-99 is a computer controlled equalizer with most of the functions operated by a remote display with microphone or something called "light pen". I didn't get either of those with my SE-99 and was willing to make replacement parts as some AK members did. However, now I'm afraid some part(s) inside the Sansui are damaged or slowly dying and if it's a microprocessor the whole thing might not be repairable. In this case, perhaps I should return it or open an epay case; OTOH, if such a behavior could be easily fixed I'll prefer to go this way.
