This rare NOS 6H30p-DR Supertube includes gold grids and is the absolute top grade of the 6H30 tube type. To be certified a DR grade this tube had to pass lengthy and rigorous testing meaning it is much better than the 6H30P-EB or EV versions. Its original use was in critical space and military applications within the Soviet Union. This is the same 6H30 Supertube offered by Balanced Audio Technology as their premium replacement. The 6H30 tube type is generally not compatible with 6922 and ECC88 tube types. The 6H30P-DR tube is also known as 6H30P-DP and 6N30P-DR. View the 6H30 tube data sheet.
