Hi!
I have a Keithley 2612 SMU with a broken channel, so I'd be very happy if someone has that board as a spare and is willing to part with it.
Unfortunately, the 2612A modules one can find relatively easily on eBay do not work in a 2612, as I have tested. They do fit mechanically and the power supply seems to be essentially the same, so I think a digital board of a 2612A would yield me a working meter again. Therefore: If you happen to have a Keithley 2612A digital board (or a complete device beyond repair), I'd very much like to buy that off of you.
