I have 21 pieces 6BK4C that are removed from equipment. I would like to
sell them as a lot.

These were tested good over 4 years ago. I donot currently have any way
to test. I guarantee that one third will operate. I will refund your
money upon receipt of the defective tubes. All I ask is that you let me
know if there is a problem within 10 days of receipt.


Please email me if you are interested at .

Thank you
