My fellow Crack heads I was lead to believe the driver tube does not change the sound on this amp. Possibly misunderstood as I thought they are used in the gain and not a buffer stage.

My experience is that on Crack driver tube makes about 40% and power tube makes around 60% impact in terms of tube rolling.

You need a good power tube to set up the backbone of the sound, then use the driver tube to fine tune the sound to your own liking.

Hey guys I thought I saw this posted around here but I haven’t been able to find the original post - I have a 12AU7 to 6SN7 adapter in my Crack from TubeMonger and it works great but it doesn’t look that great considering it’s a stark white ceramic color. I know it’s probably trivial but someone mentioned someone on the forums makes custom metal 12AU to 6SN7 adapters. Does anyone happen to know who that is or if not where I can get some? Can post a picture to explain if needed.

Deyan makes excellent plastic adapters, but he doesn't seem to make metal adapters. If you are looking for metal like adapters, I am not sure if Woo makes 12AU7 to 6SN7 adapters, but I find their adapters look great with white ceramic base and a metal ring, their prices are ridiculously expensive though...lol

Show my Shugaung cv181-z with some Sylvania 6080 which sounds amazing with my ZMF Verite Closed sporting some fake Audeze LCD pads I got off eBay and no more Zmf house sound. It's a bonus when I actually don't think about listening to the Abyss 1266.

Ah looking for all black metal adapters. Ceramic is nice for noise but I’ve never seen them in full black.

My tubes base is white so it works for that tube.

Glad USPS forced my hand to refund the seller. Now I can enjoy it.

Hey I just got shocked by the 6sn7 adapter my finger slipped an touched the metal below the base didn't hurt but gave my finger wake up. lol

I am glad that you are ok, I think i have the same adapter bought from Garage 1217 on Ebay. The first thing that i noticed the metal that exposed at the bottom, it is hazardous to your health so i hacked it by cutting a part of plastic tube for medicine to cover it. It fits perfectly and prevent you from touching the base.

I'm doing that today. It's a nice adapter but I got kids. Thanks for tip. The clear orange adds flare.

The black rubber caps that fit on the end of a brush handle work really well on these adaptors. Just cut the bottom off and they are just about a perfect fit and positioned right they will just overlap the base of the tube a little..

These are the sort of things I mean. Can't remember the diameter I bought. Long time ago. Measure the adaptor.

Only time I use brush is tall grass toothbrush and hairbrush. Not sure what describes brush in the UK. Same words different meanings between us.

This sort of thing. Metal handled sweeping brushes often have one on the end of the handle:

We call it end caps. So in UK it's brush?

hey, fairly new to OTL tube amps and assembled a crack a few months ago. Actually the experience with the HD800S I have is kind of underwhelming. Sounded pretty normal to me, despite all the hype the crack gets with senns cans. Was just wondering maybe I should change the stock tubes? I have no experience with tube rolling, but if it could improve the sound a bit (especially the soundstage, I mean the crack just took away all the soundstage my HD800S had..). Any advice from experienced users would be nice. Thanks in advance. Oh I use a Aune X8 dac magic as my dac with burson vivid op amps.

Yes get RCA 6sa7g to start with also get the amp modes more here's inside of mine. I bought this from a member. It's awesome with my Verite open and closed. My HD6XX is way better on this amp them any solid state I tired. For $690 buck was worth the chance on it.
