hello
I have a question about power tubes
like 45, 2a3, px25 or 300b.
If you take a tube opration from the paper
is ther a common rule what happens with the sound if you increase or lower the b+?
And what is happen soundwise as you play with the current ?
what gives a brighter sound and what gives a warm and more body to the sound.
