One Pair of NOS GE JAN 6414W preamp tubes. Drop-In replacement for 12AY7s in your Tweed Deluxe or Tweed Bassman. These are: (1) New-Old-Stock (2) General Electric (3) Joint-Army-Navy 6414W. The "W" designation indicates that they are capable of withstanding higher voltages than normal. I've sold dozens of pairs with wonderful, toneful results. I have used these for years in building my Buffer2 on my website. NOS are BETTER. No, I cannot/will not ship overseas.
