Mine has 6HJ5. I just found the history. You are correct. So it appears Julius himself worked on this amp. What makes it likely those are his initials is that any amps needing service back then were sent to him personally.
Cool.
I'm not clear on power rating though. The article I found states it's a 40 watt amp but doesn't say whether total or per ch.. The amp has 4 6HJ5 per side.
