Soooo . . . Got the 1821 unit back in, things went well at first, then suddenly the display cut out. I can't get a sausage using the timebase in "Normal" mode, but using the "Auto" setting it comes up fine. I have also started getting that previous problem with the EHT again. I will build an EHT Probe at some point this week and I will measure the rails tomorrow.
There's thunder and high humidity here just now, so will wait until tomorrow to get going. Hopefully the weather will be a bit fresher. And hopefully I will be too!
