As for tube rolling, 6DJ8/6922/ECC88 are fully suitable for replacement for differences in musical taste. The JAN-Sylvania 6DJ8 is an very nice tube with good sonic capabilities and would be a nice candidate for this tube amplifier for tube rolling. A version of this 6N11 tube is also produced in the Russia under the designator 6N23P (Russian: 6Н23П).
