Refreshed after a nights’ sleep I jumped back on the New G Sunday morning. Adjusting the trip switch reset was an easy matter. Then it has to be checked that this adjustment didn’t throw another one off. I usually chase these trip adjustments back and forth til I get it right. The A side was still not picking up.I ohmmed the wire from the reverse switch to the leaf blade and had continuity. ???? Was this replacement contact I got my buddy in California bad? I had pulled that blade once and polished the contact area. It wasn’t sagging loose. I pulled the pinbank, lifted the contact block and removed the white plastic contact. By gosh, I was going to ohm it from the tip to the bottom. That is when I noticed a very small piece of plastic covering the bottom metal contact that rides on the leaf blade. When I pulled the contact out of the little plastic bag it was in somehow this piece of plastic got stuck in just the right place. Feeling like a chump I put everything back together minus the plastic and watched the mechanism merrily pick up A sides.
Now I can check the “corners”; A1/A2 and K9/K10. If the mech will pick up these four selections then the contact block alignment is perfect. Right side K10 was having trouble. K9 was picking up every time but after rejecting it and reversing the mechanism just didn’t seem to be travelling far enough left to lock onto this spot. I moved the right side reverse switch bracket an 1/8″ to the right to allow the mech to get a little more momentum coming off the turn and that did the trick.
Just for the heck of it I pulled the amp tubes and retested. The 6SN7 was weak. I didn’t think this was causing the hum which seems to have gone away but it got replaced nonetheless. So I seem to have a working machine. Onto other things.
