Everyone is talking about copper insulation inside the vario capacity
bottle but two years ago a German made bottle installed in my PW6 had
steel material -- the compass went nuts. The bottle had to be sent back
for demagnetizing !!

I'm fiddling with a Bohli Variometer that originally had a TE compensation

I've got a Bohli - it's a nice vario. You've got lots of
answers to your insulation question, so I'll just add this -

1) When you add the copper scrubbers to your capacity (good
idea), first pull off any metal buttons on the top of the
scrubbers. They'll corrode and put junk into the Bohli.

2) I had to disconnect the Bohli from the TE probe as it
interfered with my older Ilec system which uses a small
internal capacity. It wasn't the Bohli's fault, but the
large capacity on the mechanical and the small capacity on
the electric produced capacity to capacity crossflow that
interfered with the Ilec.
