Sorry,but the different language don't help me.
What you intend for"a power tube goes cherry"?
For your experience how time is power tubes life on Power serie?
this is the resistor in the bias point? if yes,you are not supposed to adjust the bias correctly.check the value of this resistance and change it.it will affect your sound.be sure to use the same brand.
