Best way to break in a tube amp? With cheap tubes?
What's the best way to break-in a tube-amp? Should it be left on continuously for a few days or in separate time-segments? If I have cheap tubes and better tubes, should the break-in be done with the cheap ones? Do the tubes themselves need to break in? Would you do anything differently for a preamp vs. a power amp? Thanks in advance for any thoughts on this.
