Have any of you tested your GL KT77 reissues for grid leakage. I had my tester out and thought I would run the quad I have through the paces. Emission was strong but grid leakage was questionable for all four of a quad. I ran some JJ KT77s through and they did not act the same. These GLs are not that old (new in September and not always in the amp) so I was wondering if maybe this was inherent to the GL make. Any input would be welcome.
