I've never seen one but have read that they exist as they were around in the mid-late '60s.
So, anyone have any in their collection?
Thank you

One popular Guitar Amplifier brand was "Harmony" and no doubt they had tubes so branded.
Another popular Guitar amp maker was "Silvertone" and thereare definitely many so branded around.
Actual manufacturer could be anybody.

Didn´t find Harmony tube pictures but here´Silvertone, same thing.
Tubes were often made by Sylvania, go figure:

Looking at the style of the "H" I think that the 12AU6 in this Harmony H-400 has "Harmony" written on it.

Defnitely, good catch.
Way back then, those were "department Store" House brand amplifiers, TVs,etc.
Sometimes same manufacturer supplied 2 or 3 different chains, each under own House Brand.
Imagine buying today a WalMart or Target branded product.

I guess I should have provided some background. I have a Harmony H400 amp but mine came to me without it's original tubes. I know their tubes from factory were Harmony branded. I have seen two different references that one guys original tubes said USA and another guys original tubes said Japan. Both showing Harmony brand. But neither provided pics (or at least good pics) to show the markings on the tubes. I'd like to find some of those original tubes or
good pics of the original tubes showing markings. That's why I'm asking the question.
Thanks again everyone.

In the USA the Silvertone brand was the Sears Roebuck department store brand. At one time Sears was one of the largest companies in the world, at one point it had more mainframe computers than the federal government. They could contract any tube mfg anywhere to brand their tubes, nice contract for Sylvania I'm sure!
