Cheap and rugged power amp tubes.
They were the stock power-amp tubes in my RedBear Mk 120, and I just stick to them. They cost low and if you buy them from a good seller they last really long. Even the best ones made in the old Foton factory are quite reasonably priced.
I use the ones made in the Foton factory. A quad of Foton 6P3S-E costs just $6 to $10 more than the Sovtek 5881 but in terms of longevity and reliability they blow the Sovtek 5881 into weeds. My Sovtek 5881 tubes went poof in just 5 years, on the other hand my Foton 6P3S-E tubes are now 8 years old and still going strong, that too in an amp that is used for doom metal where the power amp overdrive is everything.
