does the board have to be grounded to the encloser and do the jacks have to be grounded to each other.

Yes!

Did anyone uh....replace the 100r resistor at pin 6 (or whichever is the delay time pin, totally forgot) with an LDR that's controlled by the same LFO or another lfo? Cause that could make for a pretty sweet flanger.....right?

Replacing the 100R with a LDR would increase the delay time of the PT2399 to such an extent that it would no longer be a chorus, but a delay with modulation (not a flanger). The whole concept of Little Angel was to keep the delay time to a minimum by using that 100R resistor and modulation pin 2 instead of pin 6.

The whole concept of Little Angel was to keep the delay time to a minimum by using that 100R resistor and modulation pin 2 instead of pin 6.

I only suggested this for 2 reasons. First being that I'm remembering back to the echo base/other delays with modulation, that modulation is achieved by "wiggling" the delay time pot. Secondly, I just built a small clone, and i noticed that when I played around with the delay time, I either got modulation or flanging (depending on the timing cap). I also noticed that some chorus pedals out there have a "delay time" pot, I figured it might be an interesting addition.

I built this yesterday (pictures in the "pictures" forum). It really sounds nice and the PCB layout is good.
Big Muff, Trotsky Drive, Little Angel, Valvecaster, Whisker Biscuit, Smash Drive, Green Ringer, Fuzz Face, Rangemaster, LPB1, Bazz Fuss/Buzz Box, Radioshack Fuzz, Blue Box, Fuzzrite, Tonepad Wah, EH Pulsar, NPN Tonebender, Torn's Peaker...

Olá para todos , meu nome é daniel, sou brasilieiro .

Acabo de montar o little angel chorus, fiquei surpreso com o resultado, fantastico, achei muito bom.
A unica mudança que fiz foi usar os pots de 100K, o restante dos componentes são o mesmo do esquema original.
Me perdoem por não escrever em inglês  pois não domino o idioma, e  não sou favoravel a o uso de tradutores.
Agora posso tocar Nirvana... rsrsrs....

Abraços a todos e muito obrigado ao pessoal do forum que me abriu uma porta para um pedal complicado de se montar.
Abraços e Felicidades..

I think he likes it! He used 100k for both pots. Now he can sound like Nirvana.....obrigado!! ;D

Yes that was the same impression I had.. Though I don't typically associate Nirvana with chorus..  ;D

Hi, everyone, my name is Daniel, I'm brazillian.

I just mounted the Little Angel Chorus, I'm surprised about the result, fantastic, I found it's very good.
The only change I made was to use 100k pots, the rest of components are the same as in the original schem.
Sorry for not write in english but I don't dominate the idiom and I don't like using translators.
Now I can play Nirvana... rsrsrs...

Cheers to everyone and many thanks to the forum staff who has opened me a door to a pedal that was complicated to build.
Hugs and congratulations!
Daniel Venticinco ;D

built it, loved it, but tweeked it: was experimenting with different value pots off of pin 6 to go from chorus to delay and, ummm, hooked up a 24v adaptor instead of the usual.  :icon_redface: poof! so a quick check of everything tells me that the only components i used not rated for that much were the two 10uf in the LFO & the NE5532.  I can't find anything on the 2399. did i nuke that as well? i built this on perfboard and i'd like to think i don't have to redo all that. i replaced the 5532 and it passed signal again, but there's a loud buzz.  i only have one more 2399 so i don't wanna swap that in if there's something else wrong.

pop out the PT chip and turn the unit on and make sure you are still getting 5V on your regulator. I believe the lower rated regs can only tolerate 15V (don't quote me on that). Your regulator may have saved the PT, dunno... I'd assume I blew the PT if the reg works.
