A complete test of power tubes needs to include measurements under actual operating conditions. For me, testing and matching is a two step process. First, I test and match the tubes for transconductance using a Hickok tester. Then I install the tubes in an operating amplifier and match them for cathode current.
The Maximatcher can test and match power tubes in a single go, but it's fairly expensive (and currently out of stock). In your situation, a transconductance test is sufficient. Many sellers on the big auction site use this approach. I would include one set of matched spares with the sale, then sell the remainder separately.
