About 2 months ago I had to refurb a Tek TG501, everything was badly oxidized, see attached pictures. Not wanting to take unnecesary risks as lots of parts were unobtanium, I replaced every socket and brushed all the ics by hand. --- End quote --- The leads take solder like new. Although they don't look like bare copper, more like grey-ish brown. At first i thought they were still corroded because the leads looked dark but they take solder perfectly well. --- End quote --- try putting it in the ultrasonic with alnox, I found it makes things shiny like metal transistors that look old look newer, and unused solder/crimp connectors too (i.e. spare blades on a connector). A few times I though "holy shit, how the FUCK am I gonna get all this looking decent" but I am pleasantly surprised after the ultrasonic to only a few patches being bad, which I can hit with neverdull or something. But beware ink disappearing. |
