I would save my money.
The newer PA211 might have better specs, or whoever's selling it might claim it's better. But there are posts (you'll have to search) claiming some of the new production PA211s out there aren't as good as the original. I know, because I considered buying one to try building a dual-mono (one transformer per channel) power supply for my Last PAS. After reading what I read, I passed.
If you want an inexpensive upgrade, tweak, or whatever you'd like to call it, I would suggest adding capacitance to the filament supply. You could replace those two 2200µF caps on your board with the Nichicons I've linked below, but there's no need to. As long as you have room, you can add the extra caps, and simply wire them in parallel with the existing caps. Secure them with a bit of silicone, and you're good.
I'm not one of those "magic wire" guys, who claim they hear major improvements with every change. But I've never failed to hear an improvement when adding a significant amount of capacitance to a stock (or nearly stock, as yours is) PAS filament supply.
Good luck, and you're very welcome. Thanks for saying "thanks"!
