1968 Motorola works in a drawer

Thank you! So adjust by rotating? I took a close up pic of the ones on my set. I've not seen this style before, on my other TVs they were more obvious.

Update: figured it out. Convergence procedure went well as did grey scale. Purity was difficult but found a decent compromise.

Set makes a great monochrome picture, but colour is kind of weird, tends to smear across the screen when there's a block of one colour, almost like a shadow. Picture a bit jumpy after convergence procedure as if one of the convergence pots was dirty.
