I've noticed lately that when I'm done playing, the tubes in my 6505 will, for lack of a better word, tinkle and chime for about 10 minutes as they cool down. I haven't really looked to see exactly which tube is doing it, but I have checked my bathroom faucet about a dozen times before figuring out where the noise is coming from.
Is this normal? Amp sounds/works perfectly fine.
Odd thread title, eh?
I know the sound you're describing, but I wouldn't say it's normal. Maybe it's the sound of the caps bleeding out?
