Hi Paul,

Thanks for your advice. I should mention that the noise is only present when the reverb is on. Perhaps it's caused by poor contact.
I don't need matched tubes because I've modded my amp to allow each tube to be individually biased. But I do want to install tubes of all the same type.
I don't understand how the problem could be in the output stage when the noise disappears when I turn the reverb off.
