I think four of the pins are gold-plated and one (the ground) is solder-plated. Here's a spec sheet: http://www.circaent.com/assets/Telec...ule-Series.pdf
I didn't notice anything on this spec sheet about gold plating, but I did see it in a technical requirements document.



Is there a manufacturer name on any of the old boards/cards in your first post? The capacitors are aluminum electrolytic capacitors. Those black brackets on the transistors are heat sinks, and they're aluminum. The boards are old -- you can see the traces were put down by hand.
