Hi all,
I bought a used Audible Illusions Modulus 2B from a seller on Audiogon recently. Great pre, but with my tweaky nature, I had to modify something! I've replaced the main PS 'lytic (Nichicon NT), the B+ 'lytics for the line and phono (Elna Cerafine), and the phono coupling caps (RelCap RTX). They were in the parts bin, so I figured what the heck.
The unit sounds noticably better, save for an annoying 60 Hz buzz that wasn't there before. The lead lengths of the caps are almost exactly the same, and my soldering work is very good.
Any ideas what I screwed up? I've modified tube preamps before with nothing but wonderful results. Very frustrating....
Your help is appreciated!
