Yup, the jacks are 1/4" (and rear inputs are RCA). Right, it's hard to get the dimensions from the pics alone. It's roughly 10" tall total, maybe 11" deep, and 8" wide. And the power light on mine is green.

Many thanks. Jade/Green - makes sense! Enjoy!!!

Pauly, when did you order your unit? I ordered mine on 12/22/08 and have not yet received notification/invoice.

1/18/09 is when I first e-mailed them saying I'd like to purchase. They replied that it'd be at least mid-Feb before the Jade would be ready, and I didn't give them money until last week (Tue. I think). They were pretty responsive to e-mail (me asking impatiently when they'd be ready ), I'd suggest sending an inquiry to the address that appeared earlier in this thread.

Seems like you're the first to get a production unit! I'm looking forward to reading your review with different tubes!

That Jade looks quite nice! And having a look on Audiotaylor's webpage, I could find some pics of the Headmonitor 2 (although, strangely, only in the Chinse version of the web). which also looks promising:

Yeah, that's one of my next steps. I'll probably start by trying to find the same tubes that Skylab ended up preferring. But I don't want to rush into it, I figure I'll burn in the stock tubes first, and play around with the two outputs of the Jade for a while, to get used to how it sounds now. Then I'll do some rolling later - though I probably won't go crazy with it.

Ok the first question with tube rolling is exactly what sort of tube to use. Skylab says the power tube is 6AS7G, which is consistent with the Jade's manual that says 6N5P, and the stock tube which is labeled 6N5P. From what I understand (via google search), these are exactly the same thing, so no problem there. (As I said before, I'm a tube newbie, so you experts please correct me if I say anything wrong here.)

However, Skylab says the input tube is 12AX7 and he used a slightly lower gain 5751 - consistent with this table of the 12AX7 family I found. However, the Jade manual says 12AU7, which is a very much lower gain from 12AX7 or 5751 (again see the table). I don't see a label on the stock tube itself, and I have no way to test it to see what it actually is. To add to the confusion, the Jade manual shows a picture (figure 2) that says 12AU7 and ECC83 on the same tube - but ECC83 is, from what I understand, equivalent to the 12AX7 (and ECC82 is equivalent to 12AU7).

So, which is it? Audiotailor folks, are you reading this? Can you clarify?

If the production version uses a 12AU7 that is a change from the prototype I reviewed, which no question used 12AX7.

Thanks, Skylab. And I think I was somewhat mistaken earlier about your issue with the power tube socket - I thought you meant it was too close to the transformers, but maybe it was really that the socket was too low, below the plane of the casing? If that's the case, it's not a problem now, the top of the socket is flush with the metal case. Is that how it should be? (as opposed to being above, actually sticking out of the case somewhat)

Yes, I am sure they fixed that.

Have you tried the military 6as7 - the 6080 in there?

I currently have some and fully willing to take them out of the fs section for you to try since right now I have no intention to use them.

Is there still promotional pricing available on the Jade? What is the total cost with delivery to the US?

Thanks,

JP

Sorry ! It is 12AX7 not 12AU7. Our staff forget to correct the diagram.
I had test it with 12AT7 & 12AU7 today. It work fine on these tubes.
