Where to test tubes?
Thanks in advance for the help. I have a bunch of NOS 1970's 6h30 tubes that I want to have tested to identify which are the strongest and match each other best. Is there a service or person that you trust that I could send them to for evaluation, resulting in detailed report on each tube? Happy to pay for the service, of course.
