Audible Illusions M3 capacitors

Hi Everyone,
In 1993 Martin DeWulf wrote a review of the Audible Illusions M3 preamp. In there he talked about removing the 4 polystyrene capacitors in the line stage to add "more fuzz on the peach". I have been trying to identify those caps in my M3 without any success. Not even A.I. will respond to my emails. Can anyone here help me with my issue. My electrostatics love the fuzz.
P.S. I do have a 2 yr. electronics degree and know how to work around tubes.
3Owgary, Just read your message. Please email me at and I'll explain removing the bypass caps in your M3 preamp. Regards, JC/AI technician
