Description

Flat rate shipping regardless of quantity! If purchasing more than one tube make sure you use the "Add to Cart" option before checking out.
All tubes test strong (nothing marginal) on a recently calibrated I-177B dynamic mutual conductance tester.  In the off chance you get one that won't work for you I will happily refund the tube.
Pictures are representative.  Some tubes will have little dust, missing paint, etc. but physically and electrically sound.
