We have been cleaning out our club's hangar's store room and are
finding all sorts of old and odd items, no doubt left over from some
old and odd members.

I was curious about two of the items and wondering if anyone can shed
some light.

- A clear bag containing two smaller clear bags. First bag is marked
"Netto" and contains what appears to be a very small brass valve with
~1/16" aluminum tubing coming out of each end. It might not be a
valve and might not be tubing. Second bag was labeled 0.003 (!)
stainless steel wire (almost thought the bag was empty at first). How
are these used in a Netto system?

That's not wire, it is tubing, used to create a calibrated leak
for a netto. Perhaps valve turns netto leak on/off.


- Cambridge Model AU-22 - Cigarette sized black aluminum box with a
speaker, two knobs, circuit board and a cable coming out of it.
Complete with a repair tag labeled Cambridge Aero Instruments, Warren-
Sugarbush Airport. I have never heard of this model number and
Google doesn't turn up any hits. Is this an early audio vario? What
does the connector connect to?

Its an audio, hooks up to early Cambridge Variometer products.
Uses a unijunction oscillator !


You should see the stuff in my basement !
See ya, Dave "YO electric"
