Hi Rich,
It looks much the same as it did here;

There's a power switch on the front of the PSU now, but that's about the only difference.
The TechTube valves are very good but rather expensive, I bought the more expensive versions where the two halves are closely matched. £40 each!
Better than 5751's?... I'd have to say yes (I would, wouldn't I
) but not by much. Worth the extra expense?... probably not, it depends how much money you want to burn! They are very, very cool running and will probably last for years though, also, the website is still open ATM so it appears you can still buy them for the time being.
I've no idea what they've done to the RIAA response, I've never checked as I don't have the gear to do so. There's a couple more tweaks I'd like to incorporate into it and then I'll look into getting that sorted out.
Cheers,
Mike.
