anyway, stuck it in my GA-5 - stock except for removal of the wire meshes and wood cord box -
and I like the sound of it very much!
Based on a quick test run I find the Jensen less efficient and the sound of the amp fuller and more articulate at a lower volume - does that make sense? The break is just as sweet - again, though, at what I perceive to be a lower volume than the stock Goldtone/Weber. With the Weber it seemed I would kinda hunt for a sweet spot in the guitar/amp volume settings. The Jensen sounds "better" throughout the dial.
Admittedly, the Weber is not broken in - the Jensen is 40 plus years old!
A few years ago when I had my first flirt with cheap Harmony amps I learned that the 8J11 was stock on some vintage Gibson amps - maybe something to do with it?
Anyway, I'll leave it in for now.

Is your Jensen 4 or 8 ohms? If it's 8 ohms, it will sound better and be more efficient if you switch the 8 ohm tap of the output transformer to the speaker jack.
I don't know what was typically used in Harmonys, but It looks like vintage Gibsons typically used 8 ohm 8"s.
