I seem to remember GT813-817, where G was for Germanium. These must be new, improved versions. Hfe=10 and 5uS switch on time sounds very exciting. Not to mention how those pesky reverse currents love temperature. I think they were intended for switching applications and voltage regulators but were also definitely used in audio. Wouldn't touch them with the proverbial barge poll.

Where are the selenium rectifiers? That's just not hard core enough.
