Compression Trimmers

ARCO mica compression trimmers. This new line of trimmers fills a big gap for those needing variable capacitors in the 1,000-2,500v range.

Plus they have a 1/8" diameter x 7/16" long shaft for knob control and a panel mount bushing. The ceramic body is similar to the 30 Series ARCO, 7/8" x 15/16".
