it used these weird custom Fluke analog switch chips, 700013. several of them failed, so I made tiny PCB replacements!

@tubetime Wow. You an inspiration for those into electronics repairs. I'm already happy when I can identify and switch out a bad cap or transistor..

Fixing old equipment is doing a good deed
