EgoDriver Issue

[teknoman2]

I finally built my first stompbox but there is a problem,

when I plug it in and I turn it on there is no sound...

When its off I can hear my clean from my guitar.

I upload some photos so you can see what is the problem..

[teknoman2]

Another two photos.

Also when I turn it on the two diodes D3 and D4 doesn't light

instead the LED when I turn on the footswitch it works.

Sorry for my bad english and description.

Aslo I took the multi-meter and I noticed that the IN is grounded is that correct?

[murdog47]

Run a wire from the input ground (sleeve) to the output sleeve. When unboxed the output needs grounded. When boxed your enclosure grounds it for you.

And your clipping LED's are probably working fine...you really have to crank it and dig into the strings to get the LED's going on this circuit.

Thanx mate I will try it

Hope it works.........

[teknoman2]

I just did it and it doesnt work

I connect them like this as you said,

Check the photo.

Am I wright?

[murdog47]

Yes that's correct....if you have a digital multimeter post some voltages at the IC pins and transistors.

[teknoman2]

ok man wait 15 minutes

[teknoman2]

At the Ic pins its 4.48 Volt at the transistors I dont have anything....

[murdog47]

4.8v at all eight pins? No voltage at the transistors is no good. Do you have an audio probe? I would recommend making one of these ( http://www.madbeanpedals.com/forum/index.php?topic=1140.0 ) You get the audio probe and can test your circuit before hooking up a 3PDT and jacks.

[murdog47]

If you have one start checking the circuit and see where you loose signal.

[teknoman2]

I had 4.8V on the 1-5 and on 4-8 so it is 9.6V if we sum them up.

What do you think is the issue??

Do you have any idea?

[madbean]

You should be reading 9v on pin8, 0v on pin4, 4.5v on pins 1, 2, 5, 6, 7 and between 3.5-4.5v on pin3.
