When I picked up my Sansui 8080DB, it was in a pretty "abused" state. I knew it was euchred when I bought it and was planning to rebuild it anyways. The basic unit was there, but anything resembling how Sansui shipped it in '78 was long gone.
I noted in pictures and Sansui literature that these originally came with shorting plugs on the "unused" phono inputs:
That's in a different model Sansui, but same idea.
They're mentioned in the owners manual as well. Meant to help prevent "cross talk" or hum on the high gain phono sections. I figured if they bothered to mention them in the owners manual, I might as well try some. It' s not like it's very expensive to pick up a handful of them.
I don't use either phono input (preamps into the aux in), so I shorted them both.
And.......Nothing. No change in sound in any way. Ear right up to the speakers and still nothing.
Had the wife come in an do a "blind" listen as I installed and removed the shorting plugs (making sure she couldn't see).
Still nothing.
Not really surprising as my system had little to no noise floor before I had even started with the shorting plugs.
Since there was no change and I already had them, I just left them in there. Sansui put them in there originally, so installing them now at least can't hurt anything.
The package I bought had more that just the 4 phono inputs needed and their center posts are removable, so I turned the rest into essentially "dust covers" and installed them on the used inputs:
No one will ever see them, but if someone does for some reason and asks, I can make up something like "it shorts out the flux capacitors and reduces the harmonics of the input crystals for better noise floor performance" or some tongue in cheek BS like that! Just a little fun with friends sometimes....
They also satisfy my tendency towards "shiny" things.
Has to be functional, but if it can be functional and shiny, I'm in!
LOL!
