FB,
These came with the amp. Not sure where DH sources his tubes. Though It seems my tester is working fine who can ever be sure. I do not have a control tube to test. That is why I inquired here. I did run my JJ kt77s as mentioned but it did not confirm or deny anything since they are a different make.
