here is my try at the gyraf 1176.....was lots of fun building, and worked the first time....calibrating went smooth too.
i used mnats(THANK U :grin: ) version g board with the oep output transformer and ic input.
the meter is a cheap dc meter with a germanium rectifier ,series resistor and cap.i changed the scale.
the sound is GREAT.no hum buzz or hiss too. im so happy with this unit......THANK YOU jakob for the project.
