I have built a Bottlehead Crack with Speedball.
When I use the GE 6080 that shipped with it, it works flawlessly.
I bought an RCA 6AS7G from tubedepot.com and it looked clean; the box certainly wasn't. This is supposedly a "known to work" from the tube-rolling forum.https://forum.bottlehead.com/index.php?topic=663.0.
I get a whine only in the right-channel when I use this tube. I've reseated it a few times to no avail. I roll back to the GE and the whine goes away.
This whine is not affected by volume levels.
Is this a bad tube, or is it "just so much better" than the GE that it is showing a bad solder joint, and therefore I should reflow all my connections?

- Passed all resistance/voltage checks
- Tube has been baking in for likely 48 hours of on-time
