300B tube death question........



Has anyone experienced the death of their 300b tube? What happened.....Exploded? Imploded? Awesome fireworks display? I'm just preparing myself for when it happens.

Also, the 300b tubes in my amp is underbiased and it won't reach optimum recommended voltage settings (volt meter should read 700ma but tube is at 450ma). The amps have manual bias adjustments only.

So far nothing has happened and the sound is fine. Should I replace them now or wait until they die? (see above question).

Amps: ASL monoblocks SET amps - (2) 300b per channel
Tubes: Valve Art 300B 98C

Thank you for sharing.

...something is wrong even besides tube(s).
do you have this problem on both tubes and both channels?
