This is for a lot of GE 6AK6, GE 50DC4, GE 6X8, Raytheon 6J6A, Raytheon 6BN6 and a Sylvania 6S4A USA made vacuum tubes in excellent clean condition in their original boxes. See the pics for condition and all that is included. 6 tubes in total in this lot. Guaranteed good. I believe these most likely are NOS.
