No I mean the opposite. From my reading, and I think you might want to research this on Audio Asylums Tube Asylum that the suffix tubes last a lot longer and are better over all than the standard meaning it is the 10,000 hr tube whereas the plain 6H30 would yield 5,000hrs. . In particular there is yet another variant the 6H30 DR which is also highly prized. It is not a tube I use or collect.
However almost every preamp or small signal tube last 2 to 4 times what the output tube it drives or effects. I do use 6922s which are cousins of the 6H30s., or so I am told. I have yet to wear out a small signal tube. Even a pair I bought as worn out still work well. OTOH Worn outputs really don't work.
