Vernier (Reduction) Dial Drives

Vernier TO Here's a variable capacitor with the reduction drive built in. This has a 5:1 reduction ratio. 380 pF max $18.00

Vernier TO Gear and ball drive reduction - 12:1 total reduction ratio. 18 pF max $15.00

Vernier TO 5:1 reduction ratio. dual section 420 pF max each. $ 20.00

Lots more variables to come as I get them photographed and posted. I've a number of 450-550 pF caps which should make it easier to build loop antennas covering the entire BCST band in one range. Inquire if you are looking for anything in particular.
