Sounds good. That would be helpful to know as well.

 

Anyone else get a chance to test this out? Perhaps in particular with a set of HD-650's as the load? Turn your Crack w/ Speedball up to around 75% max volume and then all the way to 100% and let us know if you hear a hum or noise in your headphones with NO source (NO RCAs) connected.

 I've found lot's of information on the output tube and have purchased a 5998. But what is the recommendation for the other tube? Is the stock okay?

 

Suggestions are welcome...:biggrin:

Get a 12BH7, so long as you're getting Speedball. It's super quiet and they are actually still reasonably priced :)

How do the HD650 and the Crack compare to the HD800 and the Crack? I like to have a darker headphone and a brighter headphone around and I was wondering if they'd be good foils to each other or if I'd think that one of them absolutely destroys the other.

Hey guys.

 

I currently have a HD650 and in the market looking for an amp for it. Just a question, how difficult would the crack be to assemble with absolutely no soldering experience whatsoever?

What Brunk said.. 12BH7's are renowned for having no microphonics... a great choice to have (at least one) if you've got the speedball installed.

 

I've made recco's on the 650 thread as far as input tubes go.. if you're going to be using the 650 w/ the Crack (and a 5998 for the output tube), I think an RCA "black plate" 12AU7 (or the "clear top") is a must hear combo.. stunning sound.  The Mazda CIFTE 12AU7 was bad ass with the 650, too.. great for electronica/hip hop/rock.

I completed mine last month and had never soldered or used a multimeter before the instructions are excellent and easy to follow with  lots of pictures for each step

 

Watch Tyll Hertsens InnerFidelity Crack build video for tips on how to do the connections and soldering.
