Anyone heard of Tech Instruments Corporation?


I just shelled out 600 for an OTL purportedly a Futterman H3. I've found the chronology of licensing history but this outfit is not mentioned anywhere. The underside of the transformer has a couple of notes dated 1967 and 1978 with the initials J.F. It looks to be in decent shape so I figure worth the effort. I'd just like to verify it's identity.

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.
