So I've had these AF106 transistors for many years sitting in a bag. The other day I decided to just make some rangemasters out of them. Might sell a few, but I'm worried about their lifespan. One was low gain a year ago and now it's dead. The other two are fine. I was reading these are a mesa bjts(defused junction transistors). Because of the manufacturing methods, some of the leg connections corrode. I thought about adding some hot glue to the bottom to keep air and the humid weather here on Japan out. But that might be a dumb idea. Does anyone have pointers or ideas on how to improve the lifespan or future wear on old transistors like these?
