Assistance replacing an impedance selector on Vintage Marshall JCM 800

DOH!

Sorry drewl (and all) that was something of a 'Junior' error though possibly down to a 'Senior' moment... ;-)

Thanks again

Tell us the model first next time.

I had a 2210 head, the 4210 50w 1x12 combo and even the 5210 solid state version.

Sorry about the confusion guys. In the original pic I couldn't see any possibility of another wire on there, now in the newer picture I can see the extra black under the purple. Plus the black is a lot more obvious in the picture of the correctly wired replacement switch I posted myself, duh! Thanks drewl for the correct info.

Steve as you suspect, the new switch design does not require the jumper across any lugs.
