Charge pump

[Crawf]

Hi,if i made this would it power my Neovibe from a 9v supply,and would the 25v option be too much,i run my neovibe using a 15vAC PSU but as all other pedals are on my board are 9v i'm trying to run everything from the one PSU,does this make sense? also my Neovibe sounds really good, i think, but i don't know what it should sound like,mine has quite a defined wah sound to it if the depth is up full,hard to explain i know but i'll try and post a link to a youtube video which i have still to do but will do soon.

The lamp alone will draw anywhere from 20 to 80ma, depending on which bulb you're using.
Keep in mind that your typical MAX1044 charge pump is rated in the neighborhood of 10ma.
If you upgrade the pump using the LT1054 ... your batteries won't last very long.

R.G has mentioned that he reverse engineered the neovibe into a work-alike of the univibe, while
making a conscious effort to maintain a close functional relationship with the original circuit...
which incorporated it's own dedicated supply.
Therefore the neovibe is rather picky about it's power source. It really does need it's own seperate
So it's not really a design flaw or a manfunction... it just needs its own seperate /isolated/ supply.
If you try to share common power with other pedals, you'll end up fighting hum and noise due to the
ground loop caused by the bridge rectifier.
It could be modded I suppose... but you have to wonder if it's really worth the effort just to remedy
a minor inconvenience.

just try it!

I use a LT1054 on my neovibe and I think I've read that the LTC1044/MAX1044 has been used succesfully as wel.

Btw, you do not need the bridge-rectifier if you use the charge pump. You already have DC.

Ok guys,i'll leave it as it is as its working fine with the PSU i use but i'll try and post a video as i said it sounds good but it definately has a wah sound in the vibe setting but i don't know if it's supposed to sound that way,can't get the Trower and Hendrix sound out my head so i think thats what i'm comparing it to,anyway thanks for your advice,Crawford.
