Knight-kit LC-1 Code Practice Oscillator

Found my old CPO:

oooh !  gold !  microinches thick !  :)

Someone should have taken better care of it !  It still works although it never worked that great.  The tone is grating and maybe a little too loud.  It uses about 7 mA key up and 16 mA key down.  With the slide switch in the light position no current is used key up - so that functions to save the C-cell from discharging.

I'll never sell it or throw it out though - putting it together was one of those Father-Son projects.
