I have two Eimac YU-209 tubes and bases that I recently came across. They were (one each) from two mid 70's Scientific Radio Systems SR 416S and SR 416P radio transmitters.
The transmitters were working several years ago when they were replaced by new equipment.
Are these tubes worth anything? If not they do make interesting paperweights.
Just trying to see if anyone can use these...
Thanks.

p.s. I have pics if anyone wants to view them.
