I’ve just noticed that having straightened up the alignment of the Volume and Input Selector knobs, the Input Selector’s connection rod will now run right through the middle of the Amp Board connector. So that’s why I had it over there in the first place.
Back and Drawingboard are two words that spring to mind. Ok, three words, I know.
Oh, and just in case you were wondering what that relay is doing floating around the middle of the drawing – it will be used on the Headphone Board and is there to remind me to lay that board out.
