Nice NOS porcelain 2 piece feedthrough insulators. Require 3/4 inch
chassis hole. These are great for hb tuners, linears, hv supplies, and
balanced line antenna feedthrough window plates. I have several left
but way more than I now can use so I will priority ship them at $30
for 24 insulators. I have a photo. 73s-Lew/K1NDV
