Own your own Blue Box

Our Blue Boxes need to leave their current home in Riverside, Ohio. After 8 years of restoration efforts, our C-3 is 100% working (on most days), and our ANT-18 is very functional, although needs some additional work. If you love these old trainers (as we do), we hope you will consider giving them a home and TLC.

Connector tags

Air Speed “AS” stamped metal tag in remote instrument box.

The remote instrument box includes three primary Telegon instruments, each with identical 5-pin AN connectors.  To avoid confusion, Link labeled them with small stamped metal tags.  “AS” air speed, “VS” vertical speed, and “ALT” altimeter.  Those little labels withstood the test of time. 

Spin the gyro

We recently refurbished the turn and bank indicator regulator bellows for our Blue Boxes. The regulated vacuum output is supplied to a gyro inside the turn section of the turn and bank indicator.

Refurbished turn & bank indicator bellows.

Update December 1, 2020. The bellows refurbishing did the trick. The turn and bank indicator is now working. Yea!
