Finally finished this up. It's getting an annoying high pitched whine at the moment. I'll have to trouble shoot and adjust trimmers more sometime when the wife's at work. She doesn't have a lot of patience for my guitar noises to begin with. :D

Doesn't really look that grungy in real life. It's more of a dark gray. I painted it with a red candy at first, but it didn't turn out like I wanted. Stripped it off, and just went with the plain metal look.
Sounds pretty good except for the whine.
I like the blank stripes a lot.
A fine and clean build.
Looks great in monochrome, stately and very classy!

That looks great, rumor has it, running it at 12 or 15 volts will get rid of the whine.
Looking good!

It already runs at 15V with the onboard charge pump and VReg, if you want to get rid of the wine, don't do like me, read the build doc info correctly.
Can't recall exactly wich diode, but in the charge pump setup, the 2 1N4001 that sums the two 9Volts to make 18v, swap them for Schotky type diodes, used 1N60 in mine and got rid of the whinning, sounds awesome.
Nice finish, I really like it.
Thanks guys 8)
Yeah, Rej, I used the 5817 diodes and 100uf cap per suggested mods in the build report, but it whines anyway. It could be my 1 Spot, though. When I get a chance I'm gonna try another wall wart I have. Maybe try 12volt.

Did you tried it with a battery? It would be the most accurate verification you could do.
That is something i always keep handy, a battery snap with a 2.1mm plug at is end, it never lies.
That is a very nice finish :)
My collosalus whines with the mods, as well. One day, when I have insomnia, nothing to do, and no alcohol, I might experiment with the clock capacitor.

1N5817-18-19 you have in there? That is what i use in my other charge pump equiped circuits, but they are not «clocked» effect, mostly dirt.
When i first built my Collosalus, i played with that high value cap, yes it was reducing it, but until i swapped both diodes for 1N60 it was still there. Once i swapped, i came back to the original suggested cap value and everything was running perfectly.
Mine has the wine with all the mods, but a 12V suppy got rid of it. Sounds great now!
Yes, 12v seems to be the answer! I need a better 12v psu, though. This one's pretty noisy, and there's still a very faint whine. But it's MUCH better 8)
