Thanks, Hubert. Another interesting thing from that note is that in option 004 (the high performance tube) the normal time constant resistor is 900k instead of 100k. In my second unit, that was the case until Corby changed it -- it must originally have had the high performance tube. I need to check what the value of R6 is in that unit, as I'm seeing a really, really large shift (at least 5 in 10E-12) when I switch it to LTC.
From all this, I'm guessing that the shift is to be expected in these units and doesn't reflect a problem.
