Question about Toooobs

While playing, hitting certain bass notes cause one of my power tubes to rattle. Its friggin annoying. I've seen those damper things which stop this - are there any other ways of silencing it? I switched over the power tubes yesterday hoping to move the one next to the speaker further away, with no success.

Also one of the tubes is glowing blue (which is normal), but it's only the 2nd power tube that does it. Is there a reason for that?

Lastly, I think I will replace the power tubes at some stage because they are probably at least a year old.
Will I have to adjust the BIAS if I replace them with the same sorta tubes? Or is it really not THAT nessecary.

Cheers!

Whats your tuning? When you hit certain sub bass frequency's you will always have stuff rattle, is it a head or combo?

About the tube, its ok if one of them is glowing, just leave it

powetubes should be ok for atleast 2 or 3 years total (depending on the use of them ofcuz).

and i think its smarter to let someone do the biassing, unless u know how to do it and have the equipment forit ofcuz

I was very bemused as a youngster watching the Golden Girls when Blanche said she was going to "spank her fanny" I had visions of a geriatric vertical bacon sandwich red and bruised from being disciplined!!!
