Is this still available?

price drop

Original owner of these and used them for a few years. Recently upgraded to some IE600’s and don’t use these anymore. In great shape overall, only mark I can see is a faint line in the anodizing on one of them that was there when I first bought them. Timestamp in the first pic is for Reddit as...

Thanks! They're the 30mm aluminum knobs that Parts Connexion sells: https://www.partsconnexion.com/CONNEX-80685.html Just had to drill out the mounting hole to 1/4" for the Mainline pots.

You read my mind! The knobs were the one thing I hadn't installed yet because I had to drill them out the fit the pot shafts properly. I do like the gold isolation spikes vs black tho because it matches that sweet bottlehead logo :)

Just finished the exterior of my Mainline build and had to show it off :L3000: Now to find the time to actually wire this thing up...

Lol, the key I think is selling off the stuff you don't need :) As soon as I finish my Mainline build the Crack is going to a new home haha.

+1 on the 7316 being the end of the road for driver tube rolling :)

There's a pretty significant difference to my ears between the two. Once upon a time I had 2 Speedballed Cracks and an A/B switch so that I could instantly switch between different sets of tubes in the same circuit :) The bass difference between the tubes isn't so much "quanitity" but rather...

I have quite a few 6SN7 tubes as well, along with the garage 1217 adapter. Overall they have a much darker sound signature than 12au7 types, which can be quite nice with the HD800. I rarely use them though because they tend to be more prone to microphonics and have a higher noise floor in my...

The Tung Sol 6as7G is basically a 5998 but with a bit less detail. I ordered mine from vacuumtubes.net for $20 a few months back

No problem! Siemens + 5998 is just a great combo with the HD800S. Holographic imaging, wide soundstage, fantastic mids, no sibilance, neutral but with deep bass. I rarely roll any other tubes in my crack at this point if that tells you anything :) The Amperex 7316 (mine is a Beckman labeled...

The tubes you linked to are 6DJ8 and are not compatible with the Crack at all. From my experience, the 7236 is the culprit here if you're looking for more bass slam. The 7236 is a very linear sounding tube with fast, well controlled bass, but it's flaw is that the bass lacks depth and slam. I...

Thanks! I figured I'd spice up the stock alder with some Granadillo splines to match the black top plate. I did a 6-coat hand rubbed oil finish (tung oil, BLO, varnish mixture) and I'm really happy with the way it turned out. :) I did about 4 coats on the top plate to get the hammered texture...

Getting ready to wire this thing up :) Can't wait to hear how it sounds!

Yeah that sounds like microphonics in either the driver or power tube. If the tube is fairly new then sometimes that can go away with burn in. Try leaving the amp on for 3-4 days straight to give the tube cathodes time to form.

There really is no "best", all the higher end tubes are a balance of trade-offs really. That being said, I prefer the Siemens Chrome Plate for the driver most of the time. And for power tubes I rotate between the 5998, Mullard 6080, and Tung Sol 6as7G If you've heard the Valhalla 2 with your...

Man that looks sweet! What's under the hood on that? :) Thank you! Really liking the hd800s as well. Yup! I used Krylon black hammered spray paint on the top chassis, transformer bell, and volume knob (about 4 coats or so). The wood base was actually incredibly easy, it's not stained or...

Yup! They're speaker isolation spikes from Dayton audio: https://www.parts-express.com/dayton-audio-iso-4g-gold-isolation-cone-set-4-pcs--240-720

Thanks! The cool thing is they looks awesome and they're actually pretty practical. I have a few power tubes that can be pretty microphonic and the feet isolate them really well from vibrations on my desk.

Finally finished the exterior of my build after a long time of kicking around different ideas, figured I'd post in here for inspiration :)

This is going to be a mighty fine meet :) I'm assuming there will be wifi? I have at least 5 laptops/phones I can bring with Tidal so we can have lossless everywhere

My friend is going to make the trek down with me as well, he's not on head-fi but he has the following gear to bring: Schiit Modi + Asgard Starving Student HD650 DT880 (32 ohm)

Come anyway! It's the best way to listen to everyone else's gear and figure out what you like best :)
