Good point, Chris... is any company in the USA even manufacturing vacuum tubes any
The last one I heard of was EIMAC/VARIAN. Perhaps they are still exporting large RF
broadcasting type power tubes for the powerful SW stations like WYFR, Radio Netherlands
I remember those ads years ago in QST with a picture of a baby in a diaper (nappy) sitting
next to a gigantic power tube with ceramic body and metal contact rings by EIMAC VARIAN.
The tube was far bigger than the baby.
