[Tube-Swap] For Trade - 8072 type tubes {6}

[Byron Tatum]

Hello-
    I have 6 of NIB Motorola type 4657, this is the tube that replaced the
8072, it is identical to 8072. They are packed 2 in the box, original as
from Motorola.
    I would like to trade these for any of these types. Used tubes would be
acceptable if they are decent.
