You are bidding on a Machlett ML-357B large glass tube. This tube is UNTESTED by me as I have no way of doing so. However, t is no loose glass and the tube does not rattle. On the base is a number ----437608. Shipping is $5.00. Please email me with any questions. Thanks for looking!
A friend of mine check the continunity of this tube and said it reads 100 % when he placed the ends of the multitester to two of the tube prongs, and 30 % on the other prongs.
