hey guys - as lucky recipient of the first bugbrand/haible triple chorus (or Magic Chorus™ as it is now known) i can report that it sounds freakin amazing ! in line with my solina string ensemble the effect is really hard to tell apart unless you actually a/b switch them - but can do loads of other stuff too and the eq is really gutsy (though as tom pointed out, doesn't seem to push high highs no matter what you do with it, but has a beautiful harmonic midband) and now i can put it on anything (for which read : everything), not just the solina's great but limited sounds
also, what tom's pic omits to show is the bright violet led which accompanies the effect - proper
have found a little valve compressor/gain stage which i can pop in front of it for boost for guitar signal - will try that tonight ! was zoned out into the small hours last night to the nord 3 + magic chorus combo. sublime 
top rispec to jurgen and the bugmeister !! cheers, gavin

Hi
I'm on the lookout for the JH Triple chorus PCB if anybody has a spare.
thanks

Just finished soldering the resistors to the Triple chorus board. I almost put in resistors of wrong value in one instance, and the reason was that there were wrong resistors in a pack where was supposed to be 560k resistors... I think I'll stick to buying resistors in only factory packed sets of 100 from now on.
EDIT: I now have my solina/triple chorus finished and put inside a box.
After testing it for a few days I have to say it is even better than what I expected.
Thanks A LOT Jurgen! |

Here are some photos of my finished Solina
| Description: |
I didn't have standoffs so I used this improvised method to mount the PCB inside the box.
It is adhered to the bottom plate of the box by means of screws, nuts and some glue. |

Here's some information I got from Paolo (from Italy):
| Quote: | I tell you some other findings, that could interest also other people
of the forum:
I found the TDA1022 on ebay from an italian supplier (a shop) at a
veeery low price: 1,6 € each (but with a minimum order of 50 €). I got
a bunch of them also for other audio projects. The so low price makes
me think that they are fake Until I build your project I will not
know if the chips work (they are new anyway). I send you in attachment
a picture of one. The only thing that I can say is that the number of
pins and the label are right..
The shop is this: http://stores.ebay.it/naceisrl just type TDA1022 in
the search and will appear items of 8 € for 5 chips |

Debugging the board |
|
|
I just finished building the board and no sound is getting out.
What could be standard testing methods to make sure everything is in order, like verifying voltage on IC pins, etc...

Have you connected the switches?

I have short circuited PINs 1 and 4 on the mode switch (0 based counting) so that to exclude EQ and rolloff. I think that should close the circuit for basic operation.

A quick question, probably a no-brainer for the more electronically adept - I'm making good progress with the boards I'm building, a couple of the poly box caps have high voltage ratings though, most of them are 25, 35, 50v, one is 100v, one is 400! is this likely to cause a problem?
thanks |

No problem if the voltage rating is higher.
(As long as the caps don't get too big for the board space.)
400V is quite common for polyester caps in the lower nF range.

Hi Jurgen,
finished to build the Triple Chorus board. Here is a picture:
I tested and the sound coming out is really nice! I'll play with it more extensively after building a box and front panel..
Also, the TDA1022 taken on ebay for 1,6 € are real TDA1022!!
The only problem I had (but I must investigate further and make more tests) is that sometimes 1 or 2 stages of the BBDs did not start to work. Simply turning off and on the board they will start to work again. Have you experienced something similar? maybe that there is something that prevent the 1022 to work? (the 4011 worked ok in any case) or something that I can add (some decoupling capacitors for example) to be sure that all 3 stages always work? |

I'm not quite sure what doesn't start: The 4011's oscillate, but the TDA's don't propagate signal?
Or the 4011's oscillate, but are not modulated (LFOs are stuck) ?

Finished my triple chorus! Fired it up before breakfast and am happy to say it worked immediately. It's a very lush, rich chorus. I'm not a big fan of chorus effects, but this one is really nice! Thanks again to Juergen!
BTW, I used TDA1022s that I got from chipforbrains off ebay. They work great. Not an advertisement, just have gotten good chips from them twice so far. |

Hallo
Finished my Triple Chorus. Doesn't work.
I am clumsy and /or stupid.
Mode selection goes like:
Linear = same sound as "bypass" obviously
12K (Solina) = tiny sound, bald unhörbar
EQ = Silence, EQ pots don't work
When I turn Modulation ON = Silence, even if "linear mode" is selected
It seems like 2 problems...
Where should I look at?
I feel so stupid.
Maybe my clumsy soldering technique on SMD caps...
Maybe I missed something....
and... point 0 of Mode Selector should be connected to ground? Where?
Thanks in advance for any help!

Hi Genis,
don't be afraid - many have sucessfully built this - we'll probably get yours running, too.
First thing to check: Do all opamps have -15V at pin 4?
Second thing: Which opamps have a *strong* signal (about as strong as the input signal) at their output, and which don't ?
JH.

+ man, switching in the Lambda's built-in ensemble effect, then running it through this makes for plenty of sonic motion! Will get some mp3s made over the next couple of days (too tired now, it's 1.25 am here.)
Thanks Jurgen. |

Vielen Dank
I have tested with my Digital Multimeter
and all OpAmps read -2 on pin 4
Any idea?
Maybe I did the reading wrong... |

Oh, and...
OpAmps outputs are at pin 7?

Well, your supply voltage is almost completely down, which means something is *very* wrong here.

It's official: I'm stupid
I soldered LM337 backwards
And I don't have another on my desk, so...
Tomorrow I will buy some
Should I check something else?
Can this error have injured some part? |
