Wonder Caps are original. They are film caps and don’t need replacing in terms of operational shelf life. You will no doubt hear a nice improvement in sound quality upgrading to something like Jupiter copper foil caps or other nice foil and film caps. No doubt.
Caps and Tubes
My pre-amp is an Audio Research LS-16. It was more or less inherited. It is the only pre-amp I have ever owned.
Looking down into it through the screen on top there are four large capacitors that say "Wonder InfiniCap". There are some numeric specs on them as well.
I'm wondering if these were original to the unit or added later as an upgrade. It has four fairly large tubes. They do not appear to have anything written on them that I can see. I'm wondering how to know if these are the original tubes.
This is all academic since there is little or no chance that I'd hear much difference between different types of caps and tubes but I'd still like to know if they were original or not. Of course if no one knows I can contact AR.
Thanks,
George
