over the years I have collected some vacuum tubes for system. Unfortunately I do not have a tube tester for matching, testing etc... where can I send them for a reasonable fee? thanks for any help you can offer.
Peter, the 533 is decent but only really middle of the road. the 539 B or C is one of the best hickoks, as is the 580 that is on Ebay right now too. Also, I'd look for a TV-7 (D preffered), these are a little less $ than the hickoks but the same circuit. the tubes you list should be able to be tested on any tube tester since the 1940s.
Many tube dealers will also do tube testing. A very good dealer of this kind is TC Tubes in Minnesota. I have sent Tyler and Chelsea tubes several times for testing. They do a couple of different levels of testing depending on what you need.
They also sell high end tested tubes of many varieties.
