Are you scrubbing the ICs? Might be camera angle but it looks like the ICs have been de-masked  :o

juan & cleggy have become so adept with all this stuff, i figured they needed the extra challenge of working in "mirror mode".  that's the new "genius level". ;)

A genius wouldn't have reversed all the transistors, and then had to put them back in the right way.  It's only mirror horizontally.

yep, only horizontally.

my jfet matcher has an inverted bug on it and it works great.  kudos for making it work on such a large project.  i'll try not to do any more mirrored super-genius jobs on you guys. ::)

No, just hard to see.

LOVE these. I'm wondering if it'd be a good candidate for those 2-in-1 SMD JFETs ...
