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

Film caps don't age like electrolytic caps do, especially if used well below spec of voltage and temp, so no age reason to change them.

Unless the OP has a sonic issue with them or a lot of money to spare I would discourage cap rolling here.
