Marshall "Modern" Voltage Selector

Post by Brad H » Tue Jul 18, 2017 7:08 am

Hey guys, need a little assistance. Wiring in a "modern" Marshall voltage selector on a new JMP 2203 build, and need to know which terminal corresponds to which voltage. Numbered 1-6, obviously only using three of the six (110/220/230), and of course the common center terminal, but no diagram as to which is which. Not worried about wire color, as that changes with transformer make/model, just need to know which numbered terminal goes to which voltage setting.

Thanks for the help!!!!

Easy way to test this stuff is a Multi meter connected to the common center with a resistor and adjust taps to see for your self. Trust me, knowing for your self is a lot more relieving than some one telling you info that ends up being worng!

You know what? That totally just made me realize how easy this is. I suppose I could just check for continuity between the center terminal and each pin as I change the switch positions, right? I'm talking about a new switch that's not hooked up. So I should get continuity on 110 when I have my lead on the correct pin, and the switch is set to 110, and so on. Shouldn't need a resistor if the switch isn't hooked up. I don't know, maybe that's too easy, but it makes sense in my head, haha!

Thanks for the reply!

Yes, that is the way to do it. Just check continuity on the switch in the different positions. :thumbsup:
