Does anyone have an inexpensive source for one of these? New or Used is fine. God only knows how many of these I have thrown away over the years and now I want one.
So far the best I can come up with is Fudan brand single joint air medium variable capacitor 12-365PF @~$14 delivered. I was hoping someone had some scrap ones ~$5 but they probably melted them all down long ago. I guess I could shop the thrift stores or flea markets but they probably want antique family heirloom prices for a Philco or Emerson tabletop radio these days. I'm in no hurry so unless something falls in my lap I'll keep looking for a steal.
The 5 section gives me a lot of variability to work with either singly or combined. I also ordered a single joint 10-365pF from china. Thanks for the input folks.
