Yeah, right! $450 for an UNMATCHED pair!!! Buy some NOS tubes from Andy at Vintage Tube Services [doubt he'll have Telefunken 6922's], and save yourself some money!
It is impossible for a modern production tube to match the quality control, chemical purity [anodes], precession grid windings & terminations, and the hard vacuum of NOS tubes.
