Yes, I agree that the tubes get expensive. My monoblock amps alone each have 2 300b output tubes, 1 input and 1 driver tube, and 2 rectifier tubes. When you start tube rolling from the factory supplied Russian junk to quality NOS tubes the $$$ add up quick. That said, tube rolling is fantastic. I just love how different tubes can really improve and change the coloration of the sound.
My system is a single ended triode 300b amp/preamp setup that produces only 12 watts per channel so speaker selection is critical. Even at only 12 watts, the speakers are so sensitive that you really cant turn the volume all the way up.
