Welcome back. How's the HD 800 on your Crack. Mine sounds sublime with constant use of the combo. I recently switched the stock cable with the Red cable from WyWires (just yesterday). I've been advised to break it in for 20 hours before hearing better SQ. I don't want to start the all-familiar cable debate so let's see.

I didn't choose the "crack life", the crack life chose me.

 

I had problems with the Crack and it was just repaired. I sent off the hd800 to a friend for an audition. They will be back on Saturday so I'll finally get to hear them together for the first time. 

 

And don't worry...I plan to make lot's of comments on the pairing. :wink:

Hi everyone:

 

I had my Crack with speedball assembled in India. From hour one, the first 30-35 minutes of usage are fine. Then the hum starts...first in between songs, then during the first 10-15 seconds of a song. The occurrences are completely random. The noise dies and then comes back at another place for another random period of time. I've changed the tubes, changed my HD 800 cable but to no avail. What else should I be looking out for?

 

Thanks in advance for your suggestions.

You might do best to post this on the Bottlehead forums. The advice there is spot on. GL!!

OK thanks

Sounds like interference, not a build issue. Keep anything radio controlled, wifi, and cell phones away from the crack. It can pick those things up. I agree though to go to the bh forums.

Never thought about this. I will check again. Thanks a lot.

I had a noise problem at the beginning too.  I moved it 2 inches away from the wall and now it's silent.  Try moving the amp around.

If your Crack is connected to a power strip try disconnecting other devices or connect amp in the first power strip socket.

I had one I couldn't get rid off and it ended up being a single loose connection at the tube socket. When i pinned this back into place, it stopped. Of course this could be my one obscure case. My problem was caused by having huge ass Mundorf M-Caps loose and pulling on the connections when moving from place to place.

At the outset, thank you all. I took the Crack to my office and the noise/hum just vanished. The major difference is that I switched to my LAN(hence no wifi) and plugged my Crack into a separate section of the power strip that I use. This seems to have done the trick.

Quick question about the Cardas Quad Eutectic Silver solder - what is the consensus on its impact on sound (if any)? Any advice on how to use it properly?

post #5397 of 5826

And, thanks to Head-fi'er Moatsart, I am getting my DIY friend to change some capacitors and chokes on the Crack. Details from Monday :biggrin:

Not sure about the Cardas Quad Silver, but after trying out the standard Cardas Quad Eutectic myself I wont be going back to 60/40, I really can't say how or if it impacts the sound but do think for the few dollars a couple of meters costs (which is all it takes to build a Crack) it is money worth spending for anyone who is new to soldering as imo its more forgiving to work with and anything that can help reduce trouble shooting later due to poor solder joints is a plus for anyone new to diy. Poor connections are probably one of the most common causes that require trouble shooting on the BH forum.
