I'm testing a Sylvania 6bq7a on a TV-7. Triode 1 jumps up to 50 or even 70, then drifts back down to 43. Triode 2 consistently goes to 43 and stops. The longer I wait between presses, the higher Triode 1 jumps to initially, but always comes down to 43. Minimum good value is 32. I want to sell it on Ebay but not if it's bad.
Thanks.
