Yes, although it is not absolutely necessary, it seems like nearly everyone gets better results with DC heaters on the EHHA. The gentleman who built the Rev A proto had the same result too.

Next thing you know people will want all in one stereo config with integrated DC heater supply. >.>
Anyways, I like the current board, and I don't mind running a few wires over the score line. But if the board could be in red and yellow to match the millett filament supply it would be even better! :p

Quoting myself of a few posts back:
I'd prefer black boards - I built an exstata from the last "beta" run and those black
boards are really beautiful! Far better than the common green ones.
I'd vote clear, but I love the look of the bare copper.
Black (and yellow) are apparently the worst choices for soldermask from a testing and manufacturing point of view. The mask doesn't flow and cure as well, leading to a lower resolution mask.
Apparently clear is the best, followed by green, red and blue.
You guys know what Henry Ford said when he was asked if people could have different colors on his cars? "They can have any color they want as long as it's black." Or something similar.
No soldermask and this:
two thumps up !
I think I'll take a set of boards too.
- I do not need another headphone amp (got an M³, the exstata, a Meier Audio 2Move and soon a jibos-buffer-amp).
- I don't have space to put it somewhere near the rest of my hifi-system
- I don't listen to my Beyerdynamic DT880 much anymore since I have the stax ...
Well, the only reason why I want it is because I love shining tubes and building something.
Just can't hold my hands still - especially during the winter months.
