Transistor Radio AM Tuner (CPA202)

R42.78

Suitable as the main tuning capacitor for most transistor AM radio circuits.
Contains separate oscillator and antenna sections.
Separate 5pF (min) trimmer for each section.
Looking at back side with leads at the top, lower trimmer is for oscillator section, upper trimmer is for antenna section. Left-hand lead is antenna section, right-hand lead is oscillator section and centre pin is common ground.

Overall size 20 x 20 x 14mm including 4mm long shaft. Shaft is tapped down the centre with M2.5 thread for a depth of 2mm.
Fixing holes on front face are M2.5 threaded for a depth of 3mm. Ensure any screw does not go deeper or it may foul the vanes. Holes are on 13.75mm centres.
Rotate counter-clockwise to increase capacitance.
