Matched pair, 1986 date code, excellent condition. Rare 6H30n-DP (made before end of 1992) tubes that includes gold grids and is the absolute top grade of the 6N30 tube type rated for
10,000 hours operating lifetime. The DR grade means this tube had to pass rigorous testing for space and military applications within the Soviet Union. The DR grading
does designate it to perform much better than the 6H30P-EB or EV
versions. Later reproductions of this tube (since 1999) never reached same quality level.
