Interesting subject. Any thought on Frank's question on the 6H30 tube regarding the audible sonic differences of manufacturer/dating of the tubes? Also applicable to the 6550C?
I need to replace tubes later this year. Would be very interesting to know if a potential audible improvement on the already great (glorious) performance of the ref3 is possible!
