Thanks, Doc Oc didn't fail once this evening (but I was awful, so hardly hit it - for some reason even backhand was way off as I kept hitting the upper flipper!), but I spoke too soon on the spinner, definitely needs moving again, so I'll be trying that tomorrow.
The buzz isn't doing any harm though whilst I'm holding the flipper in the up position? I've seen a few (old) posts where fuses blowing was mentioned
Still can't figure if I get to switch #22 from above or below - I can see it on the drawing but can't find a switch there
