The best bang for the buck, and relatively simple to do, would be to replace the Wondercap metalized coupling caps with higher quality caps.
Audio Research Sp-6a-Should it be modified?
First, thanks for all the input. With your help, I have found an amazing repairperson, and will write about his work after the repair.
He said he could modify the pre-amp and bring it to current levels of performance.
What do you think? Should I have it modified or leave the circuits original? What do you recommend?

Miles
