When is a 6as7 not good? What measurement makes it not good anymore? Driver tube end of life is easy to determine, but power tubes aren't to me. Besides a shorted section. If sections are not shorted, can a 6as7 still be bad? Audibley bad? Is plate voltage a good indicator of whether a tube is toast? For instance, if the two sections of a 6as7 are dramatically different, does that result in poor performance?
