I'm Gonna Guess...?

[The Ballzz]

I'm gonna make a guess here that someone has access to Marshall schematics, but is understandably hesitant and forbidden to share them. What I'm hoping for (in lieu of a schematic) is for one of those lucky folks to help layout a "paint by numbers" mod for the new DSL20. What I'm looking for is to change the Classic Gain Channel from what is currently Classic Gain Green Clean of the DSL40CR to Classic Gain Red Crunch of the DSL40CR, or change the Ultra Gain from the current Red OD2 to Green OD1 of the DSL40CR, or possibly even both of these mods.

FWIW I've been building and repairing amps for awhile, but am somewhat at a loss when it comes to designing mods without a schematic! Also, reverse engineering from the actual amp, in this case, is kinda tough without both amps on hand.

Is anyone out there willing to help a guy out?

Thanks In Advance,
Gene
