identical unused tubes from a single source, same production run
JAN (US Army/Navy) specifications made to tighter military and federal standards; ~6AK5 premium
stock boxes in excellent condition; may be minor shelf wear
contact us if one of these fails upon your initial use; we can possibly replace it.

If you want to combine tubes for a shipping discount, this is possible if you wait for an invoice before paying for any winnings.

THANK YOU for looking!
