Both tube testers I’ve used Amplitrex AT1000 and B&K 707 only have one port for an external grid wire. I’m not sure how one would attach leads to both top pins of the 596.
Seems like the 596-5U4G adapter would HAVE to be used?
While I don't own a tube tester, I feel fairly certain that you could mount it in a 596 to 5U4 adapter and test it as a 5U4GB. This should get you pretty close.

This is what I'll have to do. I think the 596 I just purchased may be quite used.
I notice a slight "haze" in the glass that my other 596 doesn't have. I don't install untested tubes.
I hope to test it on Wednesday, a local shop has an Amplitrex and lets me rent time on it. Fingers crossed

Yes, that is the best and only way to test it on an Amplitrex(some type of adapter). The percentages will likely be off due to them being related to expected values for 5U4G, but you can always take your known-good 596 and compare numbers between the two.
$300 USD per tube is pretty high but if it's worth it and lasts a very long time then I'd be willing to give it a shot. Has to be better than my current bog-standard Sovtek.

That's a Mullard 4 notch. Great rectifier and they typically last a very long time. I think $300 is a little high. I bought one not too long ago on Ebay for $125. They might not be up there every day, but often enough to snag one. The 7 notch is just as good if you find one of those. Honestly, the JJ GZ34/5AR4 is pretty good sound-wise, IMO, but many people say that durability is lacking. I only have one of them and it's been fine so far, but I probably only have a few hundred hours on it.

I'll be matching them with the new WE 300B that I'll also be ordering.
All I need now is a good pair of 0D3 but it's hard working out which make is best. It seems the regulator tubes don't make much difference to the sound from what I've read.

Thanks again for the heads up on the 596!
I got to test it Monday, and it tested slightly higher than the 596 that I have already.
I know it’s purely luck (and silly) but the graphics on the base of this tube is much more visible on my adapter!
