Nice one, guys - thanks for the heads-up! Tonerider ACII it is, then!!
Scott, thank you! I need to fill the old output jack hole with something as re-finishing the front is a non-runner; I've re-sited the output jack to an Electrosocket side mount so an on/on sounds like 'the go' there!! Just a bog standard DPDT switch?
Is this diagram pretty close?
