For Sale Dual 0-335pf and 0-20pf Poly Variable Capacitors.

These Polyvaricon type Variable Capacitors have four gangs, two 0-335pf sections and two 0-20pf sections.

The Variable Capacitors have four built in trimmers of 0-8pf each. The two 0-20pf sections have dedicated trimmers. The other two trimmers have external pin connections.

I had these special made for me by the manufacturer. The mounting and shafts are the same for all my plastic variable capacitors.

The Polyvaricon variable capacitors are a little over 3/4 inch square and 5/8 inch high. The shaft is 1/4 diameter and protudes about 3/16 inch. The shaft and two mounting holes are tapped metric size 2.5mm.

With the trimmers fully open and the external trimmers not connected you can get these combinations. Sections can be connected toghther for different tuning ranges. There is no tracking error in connecting them toghther.

0-335pf + 0-20pf = 0-355pf  --- With this combaniton you can have two 0-355pf sections.

With above combination and the Trimmers for each section set to full you can have two 16-371pf sections out of this Variable Capacitor.

0-335pf + 20pf +20pf = 0-375pf and one 0-355pf

0-335pf + 0-335pf = 0-670pf and two 0-20pf

0-335 + 0-335pf + 0-20pf = 0-690pf and one 0-20pf

0-335pf + 0-335 + 0-20pf + 0-20pf = 0-710pf
