- turnip1979 12y agoYou know what electronic part is hard to find these days? Variable capacitors! At the caps needed to make radios. Sure, you can buy them in bulk or at ham fests, but I've found it frustrating as a hobbyist.
- dfox 12y agoBecause they are fiddly, hard to manufacture and expensive, while solid state voltage or digitally controlled filters and oscillators are cheaper and more reliable.
- jacquesm 12y agoYou can fairly easily build your own.
- turnip1979 12y agoYou're right. I've followed instructables on how to do it (e.g. some cds and some foil). However, I am mesmerized by the beauty of some old school variable capacitors. Wish they still made 'em.
- jacquesm 12y agoWe used to call them meat mincers :) If you want good quality variable capacitors then your best source is flea markets and thrift stores, look for old tube radios that you can scavenge them out of. And if the radio is nice enough then maybe restore it!
