Default Tube gets noisy after warming up

Hi everyone,
I have a problem with a Valvo Ba, made 1944. After running for a bit more than 30 minutes it becomes the source of crackling overlaid over (white) noise. Changing tubes from one channel to the other made the noise follow along. It sounds like a bad connection.
I cleaned the pins and the socket, still noisy after a while. Should I try to resolder the pins?

Best,
Daniel

Probably a faulty valve.
