So, you've all seen it I'll bet... corroded and or stuck pins on bi pins, stuck lamps/ sockets in SCBs... Have you tried lubricating either lamp pins or sockets? NS used to sell a stinky petroleum grease as "socket saver". When I've used it, it tends to harden with heat and makes lamps harder to remove and sockets hard to clean. Someone from Vista recommended I try GB Oxgard, found in a lot of hardware stores, but when I read the label, it's intended use if for aluminum wire connections. Anyone ever tried silicone plumber's grease or petroleum jelly for this? Do I want a dielectric grease (said one factory rep) or a material that conducts?
