Hello,
I built a 2015 Collosalus and it's definitely doing something, but I wouldn't call it flanging. It affects the sound, but it doesn't move. I'm powering it via my bench power supply at 8.95V.

I am having problems with this 18v build as well, but I am getting no sound whatsoever. Thanks for the q1-q5 voltages, I will compare them to mine tonight.
I also have a low voltage on leg 1 of ic7.

Mine is a 9V build.
Did you see this? http://www.madbeanpedals.com/forum/index.php?topic=21849.msg203582;boardseen#new
Whoops, sorry. Too early this morning I guess, I thought yours was 18v.
Thanks for the link, I saw that yesterday.
Good Luck on yours, I can't really offer too much until I get mine working.
Are 3 and 2 on your manual pot soldered together?
They are not
