I have built this project http://headwize.powerpill.org/projec...bender_prj.htm on Headwize. I have to finish the chassis this week so I might be able to post some pics soon. Total cost: 150$ CDN (a small 75$ US) everything included.

Okay, the CDN$ is low but it's not that bad.

Default Headphone Amp.

Hi,

Personally I'm more inclined to favour Arren Van Waarde's design.
The 6AS7G family of tubes are far more likely to be able to drive awkward loads adequatley.
One section can dissipate about 13W easily and that could just as well turn out be a usefull attribute might you decide to try it on some speakers as well.
Ri is about 280R per section,it won't probably put out earthquaking bass but with the small noval tubes you can forget about hooking up to speakers altogether.(bar a few exceptions)
I always found the ECC88 family of tubes to be a bit forced in their representation of music in the long run.
Listening to that on headphones (I don't like to have anything other than the wife around my head) doesn't really apeal to me.

Cheers,
