replacements for sovtek 6922s


Now that Sovtek has gotten out of 6922 vacuum tube production, what's the replacement of choice for Audio Research products?

Sovtek no longer makes them?

JJ Electronics E88CCs worked fine in my ARC PH3 phono section.
What, does that mean people will be paying premium $$$ soon for these "sought-after", "highly-desirable" tubes too? Whoever thought one day Sovtek 6922s would achieve that status? Maybe I should run out and buy them up.
