Color of the Center tap wire on Marshall 3202/4203 OT??

[Denny]

Hi Guys - I have a Marshall Artist 3202 hybrid that has had a bias pot installed - I need to set it - I am not a tech, but have built several Ceriatone kits (Jubliee, Dumble clone, etc.,- with no issues and am VERY aware of the voltage inside the chassis - with that said - I can not read schematics (I'm looking into some basic adult ed classes in this area) so I have no idea where it terminates - hence I will have to trace it from the OT to the board and need the color. Thanks for your help ahead of time.

You can find it with your voltage meter, ime....and verify that finding with the ohmmeter with the amp turned off...testing from the primary ends at the power tubes to that center tap voltage point.
