Ok, I’ve ordered some deoxit, a replacement battery ( and null modem adapter ). The battery has been taken out. If Deoxit doesn’t work, is there a known part # for it? Ditto the switch? I’m hopeful this will work, but always look for a backup plan. ( I don’t know how long the leads are, now that the person recapping it took it out — I’m hoping it was desoldered not cut…) Earl
