Won't damage anything, not the tube nor the amp.
However, tube rolling eventually will wear out the tube socket.
That can (not easily) be replaced or the contacts may have to be 'bent back' somewhat to ensure proper contact.

Could that be somewhat solved with some kind of extra socket that could be mounted on top of the real one? |

You could use a so-called socket saver .
These usually add quite some height and introduce more connectors and exposed wiring.

Those will do the trick.

I have a socket saver. I can't tell any difference in SQ with it in or out. The socket in the Ember is rather stout and requires grabbing the saver or it comes out with the tube.

Hi Franz and Jeremy,
I am enjoying the Ember like I have never done with any audio device in my life, it is so much fun!!
I am considering plugging the ember into my integrated amp, which can act as a power amp. This is not going to be permanent, I just want to hear those tubes through my floorstanders :-)
A few questions regarding different matters:
1) I have skimmed through the thread the possibility of having headphone optimized filters. Is this an option for the Ember? I have a pair of He400i ;-) In general I love their sound signature, it is very sweet but I could do with a bit more sub-bass.
2) If the Ember is used as input for my amp, is there any danger/consideration that I should know before trying? I think I read at some point that people have done it, but I may have misunderstood.
Thanks!

Sorry if I missed this but is the scratchiness in the volume pot discussed in recent pages the 'scratch' you get when you bypass the caps or one that's still evident whether caps are bypassed or not?
Reason I ask is that I do notice some static noises from my volume pot and I don't bypassthe caps. It's not hugely annoying but it is noticeable when no music is playing. More so towards the upper end of the pot and or if I turn the knob quickly. Swapping tubes doesn't seem to make any difference so have ruled out tube noise.
Just wondering if it's a normal 'characteristic' of the pot used in the Ember or if a squirt of Caig Deoxit or similar might shift it?
Thanks!

@ tunkejazz:
1: The filter will be made in the future. Depends on the amount of time Jeremy has to spend on this.
2: No problem in using it as a pre-amp, the RCA line-outs are specifically designed for this purpose.
@ Jellofund:
The scratchiness of the volpot can also be heard with the input cap not bypassed.
It is very faint though and is only heard when no music is playing.
Ember 2 has an extra resistor which prevents this BUT with SOME tubes it is possible background hiss becomes audible.
Modification is possible. When I have some time I can do those mods to my Ember and make a tutorial.
Now quite busy with 3 other time consuming articles and proto typing.

Hey all,
There's a lot of great info in here and a lot of tube discussion, but being late to the game, it's hard to find the time to read through all 107 pages. Does anyone have a consolidated list of their impressions of various tubes with the Ember? This would be hugely helpful and it may already exist on the forums here somewhere.
The best two I've got at the moment as the Amperex 6DJ8 EC88 and the Sylvania 6SN7 GTB. My first gut impression is that the Sylvania is clearer with more sense of space and depth, but the Amperex is no slouch. I've only been comparing them for a couple of days, and so far feel like I could be happy with either of them. I've got a few other 6SN7 tubes, but they've gotten yanked pretty quickly since they can't stand up to the Sylvania. I've also got the Frankenember setup, but haven't had a chance to play around with it yet. I'll certainly give it a shot, but I tend to prefer simplicity.

My favourite so far have been the Ken-Rad vt-231 black bottle (great bass performance and clarity) and a telefunken e88cc (perfect all-rounder, a bit more forward than the 6sn7 tubes, for good!). |

That's what people seem to report about VT-231's in general. It's certainly true of my GE version when compared with my other tubes. |
