Hello-
I have 3 of US made { Believe GE}8950 tubes. These tubes came out of an
older shop that suffered deterioration of tube boxes.I believe they are NOS,
they do not appear used, and they test good on tester.{A lot of the other
tubes appeared unused and tested good}I have not RF tested them, however, as
I do not use these tubes.Would like to trade for solid state building parts
{QRP}or parts to build tube receivers. Thank you, Byron WA5THJ.
