Solitare!?!?  Really?!?!?!  ;)

Well... if you are that bored...
wanna design a pre-amp that uses a phase transformer to power stage, negative supply rail, PNP transistors, has reverb (brick), and tremolo, jfet opamp input buffer with gain channel, optimized intermediate stage(s), can be wired on strip board, etc, etc...  ;) ;) ;)

Only need it by 5PM North America Mountain Time today. That's when I'm off work...

Nope  8), I've been busy - http://www.ssguitar.com/index.php?topic=3561.msg27099#msg27099 (and on some valve amp design ideas.  To me -32 volts is bias, mmmokay?).
If you say theory and practice don't agree you haven't applied enough theory.

Wanna knock one up to verify the layout before Lauren starts?   8|

Could do.
I probably have all the parts in my junk.
I know I have several 386's.
I might even have that exact board she has.
The more I look at her project and the Ruby, the more I want to build one.
(Drank the Kool-Aid long ago)  ;)

I'll have a look tonight after work, see what I got.
