Hi Guys - Do any of you know FOR SURE what color the center tap wire is on the OT of the Marshall 3202/4202 amp? Thanks ahead of time.

I do not, but if you own a meter you can check for resistance across each of the three leads. The CT wire will read about half of the resistance you see when measuring across the two plate leads. Just keep measuring wire pairs until you find the one that gives you a lower reading.
