Do you think this 2x current draw is more because your A-30 is
malfunctioning, or do you think this might point to variability in the
A-30 manufacturing?

Sorry I don't know the answer to that. I was surprised the stobe
enabled current was so much higher that the disabled current for an
unterminated unit. Perhaps there is switched power to the line
drivers. Mine is a Mod 1 unit. On-line pictures show the case is
different at the static port so there may be a substantial redesign
between mod 1 and mod 4 units.

Where do you get ACK A-30 for $150+ shipping.?

I bet it starts with "e."

Thanks, Bob K.

No, while I built my mountain bike with some part sourced from "e" I
don't usually look for aircraft parts there.

The lowest price I found last week was Chief Aircraft. When I checked
today they showed $169 so either I remembered it wrong or the price
went up. I'm going to bet on remembering it wrong.

Sorry if I scared vendors with higher prices.

I returned my encoder to ACK for investigation/repair. They found
that, as well as the thermal problems I had reported, it also produced
an erratic altitude output when static pressure was slewed rapidly.
The unit was built in 1989 and the design has changed so they were
unable to replace the transducer. They are sending me a new
replacement for $140.
