More lube on the O-Rings caused lots of problems. Nozzles would drop downward at times. So I pulled everything out and started from scratch. Testing 3 new Z-Rods, 4 used Z-Rods in good shape (replaced the O-Rings) and around 20 nozzles - the proces

Hi, I'd be inclined to go with the through hole capacitor, as to surface mount it you would probably need to go for an elco (ceramics & films don't do that value in that voltage, & you'd be hard pressed to get a tant in that voltage). SMD Elcos a

I don't know. We never had craziness like this before lead-free. You should have the yellowish-metal analyzed to be sure. Guessing: You're seeing this color on the terminations of components, not on the bulk of the SnX solder connection. If that's
