These are new in the box tubes and other than to check them out they were
never put into service.

One audiophile told me that these tubes were the highest rated tubes in a
12AX7 shootout in Vacuum Tube Valley. They are as good as anything I have
ever used.

This is a unusual opportunity to own some of the highest rated, hardest to
find tubes I know of and these are in the original boxes.

What more can I say? I have two pairs for sale if you want both at $80 for 2
or $175 for 4, shipped price.

Payment by PayPal or Money Order is fine.
