at this time...no !!!
i think alot depends on on the design, the designer may have designed the unit around current new tubes.
what unit is the tubes going into ?
tried the eh(gold pin), jj telsa, sovtek. but the amperex globe/bugle boys, and the dario (7308) blew them away ( pse hl-1 pre-amp)
it i a very rude awakening when you try to pu preimum tubes from a reliable seller ( major sticker shock) this is one reason why i avoided the bat 5vki...too many 6922 tubes. that is why bat and arc moved to the new super tube.
good luck,
mike
