I take the 'delay line' from the boards. Origanally I thought there was gold on them, now I'm not sure. It looks like gold where the wires attached to the glass sometimes. I think the solder is silver solder.
I also get the crystals, theres several sorts.
They have a glass plate inside with really fine beautiful etchings on them. And gold looking solder on the cap & base edge & inside.
Common crystal& inside it. I think theres silver in there too.
Sorry about the size of the pics, still learning.... I did find out that a bad crystal will cause the 'green screen of death'.
