What i don't get is that why dont people just buy this instead?

That way you get to only utilize 1 adapter for the franken ember setup, instead of 2. 


Is that one tall enough so it can be used with the top plate of the Ember on? The 6sn7 version gets some extra height from the adapter itself...not considering buying any of them, just out of curiosity :wink:

Well from comparing the photo of the 'Franken Ember' setup to the one of this adapter, I would go out on a limb to say that this should fit quite perfectly. The F.E. setup is quite extra tall anyway. But if you get only this adapter then you will be limiting yourself to only the 7193 tubes, which have only 3 types. A lot of us like 6SN7 tubes, and I for one amd still on a bit more of a quest to find the golden one - although I like the 7193's.

That is not a problem, I already have the 6sn7 adapter :)

BTW, I should thank Johan-71 who prepared a small selection of different tubes that I could borrow and test on my Ember(it turns out that we live in the same city :)) . So far I am loving the Sylvania 6sn7wgt brown base with my Denon D2000. Tomorrow I will test the various 6sn7gt with my HE400i :)

Looking forward to your evaluations. I have an HE400 and will be very interested in your comparisons. Thanks.
PS. Sorry I didn't combine this post with the one above.

I got my 6sn7 adaptor from Jeremy along with the Ember. But I was talking about the 7193 adapter. I can be found from 7193 to 6sn7 or from 7193 to 12ax7 (and similar). Would the latter work on the Ember? As I said, I am not planning to buy one at the moment, but I want to understand the options for the future! :wink:

I'd hold off a bit anyway. You never know what might happen.

That's exactly how I feel too. I have both 6sn7 to 6dj8 and 6sn7 to 12au7 adapters. Both can be interchanged in the Starlight and Horizon as the heater voltage is selected manually. The former works in the Ember but the latter doesn't- just gave a loud hum and I quickly switched off!
This suggests that a dual 7193 to 6dj8 adapter might work in the Ember, but a 7193 to 12au7 wouldn't.
The other problem you have already mentioned is the potential importance of the extra height from the 6sn7 to 6dj8 adapter. I wonder if the 7193 adapter board will be too wide to avoid the large C2 capacitors without the extra height, which would mean rotating the adapter and not having the tubes parallel to the front edge of the Ember.
I guess this is another reason why it would be good if Jeremy could custom make a dual 7193 Ember adapter for us.

Yeah, it makes sense :)
But is he (Jeremy) up for it?

Hope so. He is busy with the power supply just now but he mentioned he might be able to get round to it later in the year.
