Hi everybody,
this *!??!* delay is working!
Scruffie, thank you so much, you saves me so much time and pain! Q4 was guilty.
Also, I've 5.5V on the pin 7 of the compander, is that too much? should I try to get 4.5V ?

Now I have my first home-made Analog Delay, I'm so happy! Again thanks Madbean to give us this kind of project: feasible!
I have the v3205 version working so I guess I will play with it a while and them make work the mn3008 version.
Scruffie (from Futurama?) : thanks, thanks, thanks ( * 1000) !

Okay, thanks a lot!
I'll do that tomorrow, it's past 2 am now...

When I probe the voltage, I thought that something was wrong with Q4, so I'm not THAT dumb...

Let's go!

And... that's it !

Thanks Scruffie.

Thanks for the answer!

Just to confort you, I've started with the MN3008 version and then I've changed the necessary components for the v3205.
I've stayed with the mn3001 for the clock because I've read a report which said that it works. I've changed the jumper and add D3, D2, and changed some resistors values.
Anyway, I have sound on pin 3 of both of v3205 chip. There's something I don't get...

Hello everyone,
I'm French so please excuse my poor English.

First, I would like to thanks Madbean for putting so many great DIY projects! I've build many of them and they're all awesome.

Now, I've tried to build the AquaBoy Deluxe. I've order 2 MN3008 and 2 v3205 so I have the choice. I used both with MN3101 clock.
After having trouble with the MN3008 I switched to v3205. But now, I think the problem is not here.
The problem is: there's delay sound on IC4 pin 3, but none on the output of the board, just clean sound.
I think of a mix problem or a feedback problem.
I've triple checked everything. I've checked resistors/diodes/pots/trim values. I don't know where to start looking for.
So, if anyone have any idea, I take it!
Thanks!

Etienne
