I cannot believe there are not quite a few shops that will repair a Marshall amp in the Chicago area. My shop is in Lansing, Michigan, a bit far for you.

yes there are shops in chicago but I want someone to show me why my amp isnt working and explain it to me so that I can fix it myself
I a do it yourself kinda guy

cant you just do a continuity test in sequence acording to the schematic?

I know the prob is in the pre amp
