I want to upgrade my Audio Research LS2B pre amp with new, top quality capicitors (and anything else that would help). I've searched the net, and had some useful info on capacitor types (Dynamicaps or Mundorf Supremes) but I need an engineer who can actually do the job. I'm totally solder and circuit illiterate, so I need someone with knowledge and interest. Anyone out there? I'm near Bromsgrove, but can travel a reasonable distance.
