REPLY:
I heard not long ago that one brand of 3-500Z has solid filament pins
as opposed to hollow pins that are soldered. If that is true, I would
recommend buying that brand if you can find it. Soldered pins are
notorious for un-soldering themselves over a period of time.
If anyone has the facts on this, please post.
