EF Johnson 2pF..14pF Airvane Trimmer Capacitor (Qty.5)On offer are 5 new (old stock) vintage 14 pF airvane trimmer capacitors, by US manufacturer E.F. Johnson. They are marked "T9-5 8043" and well made, with silver-plated vanes and connections mounted on a ceramic base. Fully meshed the capacitance is ~15pF, falling to ~ 2pF when open. Adjustment is via a flat blade screwdriver or similar, no special tools required.
They're 0.6" (15mm) high with a 0.3" pin spacing. I've used these for trimming crystal filters but they have a host of applications for the radio constructor. Beautifully made in a past age, a victim of economic rationalism. Somehow a little lump of red & white plastic just isn't the same (unless you're an electron) ...
Price Reference: Similar parts are still stocked by Ocean State Electronics in the US, and retail at $3.50 US each. Get a lot of five here, starting at a much lower price ...
About RFPlusRFPlus is back in the UK after a few months in Australia ... and starting to settle in. Unpacking continues. In the meanwhile I'm going to have to pull myself back into the black (I now know just how expensive it was to move several tonnes of stuff halfway around the world) so I hope you'll find something of interest amongst my listings. Thanks as always to all of you who've supported me by buying my spares, particularly over the past few months! For other info, visit my the 'About Me' page. If you're thinking of bidding/buying I'd ask that you visit that page at least once so you can read the 'Terms & Conditions' and a bit more about RFPlus. Click on the links below for more info ...
