1) clear two big spaces, one to do the actual work, the other to lay out all your components (using the sticky bubble wrap is great for this so they don't roll around

2) read through the crack manual, lay out all the components in a logical order, cut/strip/tin wires ahead of time if you want to (lots of prep time, but makes life easier)

3) read through the speedball manual, lay stuff out, etc. you can actually populate the boards as a separate project so feel free

3b) note the four resistors which you'll be replacing in the crack, and remove or mark them from step 2

3c) note the capacitors which will be bent/moved and mark them as well

4) start all the hardware assembly for the Crack, stop before any soldering stuff

5) go back to your speedball stuff and attach the mounting hardware there

6) lunch

7) proceed with crack assembly, omit the four resistors, and when you get to the caps look at the orientation in the speedball manual

8) recreational beverage

9) keep building

10) register for the forums at bottlehead for the inevitable troubleshooting

11) keep building

12) sleep?

13) build, install speedball components, check all the thingies

14) music?

I have tried them with TS 5998 & GEC 6AS7G. They are quite smooth & work well with GEC 6AS7G & HD 800. Both TS together may be too smooth for some, works great with bright HP's though.

Yeah, I had to work my way up to the X-Sabre.

 

In terms of other DACs below $300, I'm not sure there are many that are definitively better than the Aune T1. The T1 is very good so I'd stick with that unless you want to spend $500-600 at which stage DACs like the Matrix Mini (regular and pro) become great options (among others)

I should be getting this in few days (I have few very nice 6SN7 tubes..can't wait to try them on Crack  )

Sad to say that's one of the 2 adapters I bought that had noise issues (in fact, it was the worse of the two by a huge margin).  It was also among the 4 adam bought that all had noise issues.  Hope you win the adapter lottery like punit reportedly did - if indeed, the adapter is even the real issue.  As you guys may have noted, PB has posted several times, here and on the BH boards, that modding the circuit and using a separate wall wart to provide DC to the 6sn7 heaters is the recommended way to run that tube type quietly.

 

I have far more 12au7's and 12bh7's than 6sn7's and ultimately decided to abandon this fool's errand and to leave my amp as is.  Trace levels of bitterness remain.

Your base is looking very nice Matt, how are you thinking of finishing the top plate?

 

I am in the middle of making a case for my BH Quickie the top plate is the same dimension as the Cracks. I decided to make it a little deeper than the Cracks enclosure just in case my cap addiction takes a turn for the worse. I can always cut it down later if I want to make it smaller. That way I have the option of swapping the bases around.

So from reading what you guys have said you all seem to advise against installing the speedball during the initial build?

Also what kinda mods do you guys do, I see a lot of you changing the caps and tubes, is that all you do? Just curious smily_headphones1.gif

There are a couple of lists around with the range of mods in order of impact. Speedball is always the first on the list, but after that the common mods are:

  • Tubes
  • Upgraded volume pots / attenuators
  • Capacitors (power, bypass, etc.)
  • Upgraded RCA terminals and signal cables

 

I'm not recommending any of these by listing them though and would say that it's best to start stock and listen for a while then install Speedball. Tube rolling is fun at anytime, but has less impact than the Speedball. After that you'll have a really good sense of what you might want to do next (if anything)

Of course you can also feed it in with the Quickie like I'm doing. ;)
