I have a 121gw (s/n 180807803) with the dreaded 'disintegrating socket' problem. Surprised it took this long to fail as I use this gem nearly every day on the bench and bought it new from this site.
How do I get replacement parts for this unit? I'm happy to pay for the replacements plus shipping. I just need to know where to get them. From you? From a distributor?
FWIW, all four socket plastic 'tubes' have disintegrated, some entirely. I am using 'shrouded' probe plugs so I don't think it's completely unsafe yet, but it's getting there :-)
Also, I think I'm completely capable of replacing the parts - proper soldering / desoldering workbench here.
Thanks,
Gary
