NOS Porcelain feedthrough insulators
 

FS: NOS 2 piece porcelain feedthrough insulators. They take 3/4 inch
chassis hole. Excellent for linear amps, tuners, hv supplies,mounting
components,and for making balanced line window feedthrough plates. I
have a photo. These are very handy when you need them but I have too
many in my parts collection.
