Quite well indeed! Both are beautiful. Is that a laminate finish and if so what kind? I really like it!
Do you mean the paint? Rustoleum Mode spray. Says it is an ultra gloss finish like you get on old fashioned (or modern trendy retro) enamel ovens/fridges. I layered mine quite thick and left it for a couple of weeks to set. It came out very slightly rippled like 25% of the Hammerite effect which is what I was after rather than a piano finish:

Or do you mean the wood veneer? 0.6mm Santos Rosewood real wood veneer cut and glued on. I don't have any photos of the raw veneer from the turntable or the crack. The below was cut to do my Stereo Receiver. To gauge size the big piece centre is about 55cm / 22 inches left to right. :

I found one pic from the past that might show it better. The box on top of the sheet of veneer verses the completed Danish Oiled unit:

Its definitely came out well! It has a very classy look to it.

I was actually referring to the wood veneer so thanks for adding that! I like the hammered white finish on the top plates also so thanks for providing that info. The top plate and veneered base go extremely well together.

I'm satisfied with the finish of my BHC w/SB but the finish on my BHC wo/SB could use some work. Your's definitely gives me some ideas.

Which receiver is that? I'm a big fan of vintage receivers.

Beautiful! I've heard great things about Trio or Kenwood as they are known in the states. I have yet to get my ears on one. I have a couple of Sansuis (G5000 and AU-719 integrated) and a couple of Marantzs (2250B and 2220B). Vintage receivers are so cool! Your Trio is gorgeous. It reminds me of my 2250B with the wood case. Yep agreed back to the Crack.

Decided to swap in this old Bendix slotted 6080 tube, to see how well it paired with the Raytheon 6sn7 (which is a great sounding preamp tube!). Well the Bendix has a real solid punch and really makes the low-midrange and low end really push nicely. Like all my 6080 tubes, it seems to favor these frequencies, while the 5998's really REALLY accentuate clear and crisp upper mids and highs. The Bendix is a nice match to this preamp tube and a different flavor!

This is wayyy too much fun: Bifrost 2/64 -> Mullard 6080 + Telefunken G-73R -> ZMF Verite Closed

Love the wood :) Is that setup for banana plugs at the back?

I like all the nice customization. Solid brass Audio Note knob, all the adapters to have the cables point in better directions, black screws on the top plate. All the small things that make us enjoy our gear and the experience even more. The Telefunken G-73R looks fantastic. Is it a drop in for 12AU7? Never heard of it, but then again, I'm a noob...

Good eye on the knob :) You nailed what I love about the Bottlehead kits... doing up all the details makes for an ultra-satisfying experience all-around.

The G-73R is a rare and very expensive 12au7 equivalent. Found a (relatively) reasonably priced eBay listing a while ago. Certain forum members who shall not be named hyped them up on the Pendant thread recently, so not much availability and the current listings are wayyy out there. Unfortunately for the wallet, it is very, very nice sounding tube. So far the Mullard has the best power tube synergy. Luscious, liquid, and weighty warmth with tremendous clarity and detail. I generally prefer the 6J5/L63 style tubes over 12au7/6sn7, but the G73R is up there with the best.

Wow, yours looks great!! The tube chasing is never-ending. I did this with guitar amps for YEARS and amassed a completely unnecessary amount of tubes, of which 99% just sit in a box, LOL!! I'm trying hard to not do anything similar with the Crack, but I think I'm too late.

I went through a family of power tubes and they're all really great. The 5998 (Tung Sol & Chatham) is likely my favorite for separation, detail, and high-frequency clarity. The 6080 family hits harder in the lower end and really pushes my ZMF Auteur and VO in a good way, with lower end resonance. The 6as7g is in between the other two. A good medium.

For preamp, I've enjoyed the RCA clear top 12au7 for a long time, but now I appreciate the 6sn7 (especially this old Raytheon) with the proper adapter. I've also been interested in upgrading caps, but haven't done so yet. I'm trying my hardest not to sink any more more into my BHC, as I might be getting a TOTL tube amp that I've really longed for, so I'm trying to show restraint!!

Hello guys!

I have a problem when I use valve drivers with adapters in my Crack w/speedball.

There is often a kind of hissing/static noise in the headphones, which, to temporarily resolve, I have to unplug and reconnect the headphones to the amplifier for the background to go back to black.

This happens with all my headphones.

This is very annoying because I have to do this procedure at least 5 times during my listening session.

The problem occurs when I use 6sn7, 6f8g, 6j5g/l63 valves with 6f8g to 12ua7, 6j5g/l63 to 12ua7 and 6sn7 to 12ua7 adapters.

When I put 12ua7 type valves I don't have this kind of problem.

Has anyone had this kind of problem and managed to solve it?

I have the same issue. Although mine never resolved and I can never have a black background unless I take the adapter out and use a 12au7. I just turn the music up louder!

What bad news! But anyone with the same problem? or without it?
