I believe the AU22 is the audio control on the CVS-50:

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?



- 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?



Thanks, John DeRosa
