Well, I got it this afternoon. SN 060000016, blue, 12G. I'm happy to report that 10baseT works a treat, with a little dicking around, as detailed on the release CD. I did have to install IE5 to get it to work under NT4, but so far, it's not destroyed my machine like previous versions of IE did.
I've not yet installed the empeg in a car, but I note that the new sled design is much smoother. Should be less of a struggle in the MGB, where the Mk I would pull the plastic mounting round a bit - quality 70s BL manufacturing...
The unit's very much like Mk I at first glance, but the new front panel is very clear, and the buttons and knob get the job done nicely. The 'furniture' round the display means that the display doesn't look as 'lost' as it did on a Mk I. All very purposeful. Looks less homebuilt, which I guess is the plan. In fact, it looks completely 'real', although if it came from one of the majors, I'd have expected some kind of a logo on the plastic, even just an embossing. It's _very_ understated until turned on, when it looks outrageously funky. I may buy a blue front pane for my Mk I. Blue's cool.
The handle's sorted, too. Not a wobble to be seen.
I'd comment on the sound quality, but all I can say is that it's great at home, and, as it's improved over the Mk I, it's going to be fine in the cars. (Neither of the cars I run it in are exactly quiet - we'll see how it works with headphones and an intercom system this weekend, with any luck)
I'll probably have more to say when I've blasted a few gigs onto it. Could be a couple of hours - I'll time it.

Happy, happy Steve.

(I'm not sure the knob shouldn't be dark blue or black. Somehow looks wrong in silver plastic)
