Signal Cuts off after 5 seconds

[vendettav]

Ok so here're the voltages
and for somereason i cant get any sound out again.... 

V 9.5 (my adapter's voltage)
1. 8.3
2. 8
3. 0.8
4. 0
5. 4.4
6. 4.3
7. 4.1
8. 8.9

also the input and output have no voltage at all

45678 look good, 123 do not look good.

Is it still doing this '5 second' thing or just not working?

[vendettav]

no it stopped cutting out.. it's not working at ll now
but the other day it worked when i fixed the faulty joints, but had like DC hum... i even put the schematic back in the box and played for awhile... now it doesnt work...

[Hides-His-Eyes]

pins 2 and 3 are way wrong, pin 1 reflects that.

What do you get where R2 meets R3? About 4.5V? Are you sure R4 is correct?

[vendettav]

ok i get 4.46v at R2/R3 joint

R4 is also correct.. i'll try going thru the schematic again a bit later... anyways.. what else can i check?

Does 4.46V also appear at every place where the schematic says it should be connected?

[vendettav]

RG, i dont get yoru question, sorry... can you rephrase it please?? (:

[R.G.]

The whole idea of a schematic is that the parts themselves with their pins are drawn as symbols. The pins are connected with lines which represent zero-resistance wires.

In EE-jargon, every point connected by a continuous line on a schematic is presumed to be connected in the real circuit  by copper wire, and this collection of all points which should be connected by copper wire is called a "net".

You said:

ok i get 4.46v at R2/R3 joint

There are other places on the schematic connected to the R2/R3 joint, yes? So you need to take your voltmeter and test **every one of the places the schematic says connects to the R2/R3 joint ** and see if they have 4.46V too. If they do not, then logically they are not connected where they should be, and that can be one reason your circuit is not working right.  All points on a net in the schematic must be connected together by conductors in the board or the circuit won't work.

aaaa ooops.. what got me confused was that i missed the fact that R2/R3 is also connected to the 5th pin, c4 and r4... my mistake sir, so yeah
im checking it right away

i tried with a continuity test and everything seems to be well connected, tried the resistance test (as to see if two spots connected to each other have any resistance) and it still is fine.. all those joints to R2/R3 seem to be well done
R4 is also fine... wait! it's not fine.. both R4 and C2 aren't connected to the pin 3 somehow... faulty joint again... i'll report back as soon as i resolder it (might take awhile i can't do it right away)

[Hides-His-Eyes]

Thought so. I thought you checked these?

[vendettav]

yeah like i remember i did... idk.. still now it works.. but with a huge DC buzz but hey i've got this new Behringer Octaver and it also buzzes, i had a reverb (replaced it with the octaver) and it buzzed as well. seems it's my adapter cz my behringer doesnt buzz with a battery.. off to get a new 9v adapter tmaro!!! thanx guys i'll report back when im done with the thing and may be i can get some pics and clips even

now can you please give me what i have to be after on the pins 1 2 3 just in case so i can check and for my future reference (i might build some more of these buggers)

thanx again guys!!

Actually, if your circuit is working.... then whatever you measure is probably be close to what others post. If the circuit is working that is... 

[vendettav]

aaahh now the same thing happens again.. cz of my f4cker adapter.. which again works great but killed my pedal!!!!

now i checked the voltages and everything seems to be fine

1 8.3
2 7.4
3 2.3 (this one has to be around 4 according to my previous measurements)
4 0
5 8.6
6 4.6
7 8
8 8.6

heelp!??
it just dies... i dont know.. I think my adapter shorted or something... could it fry something?

[jefe]

Try running it with a battery.

[vendettav]

it aint got a battery clip but i'll try somehow

[vendettav]

ok i checked it with a battery.. still the same..
im guessing C3 died somehow...
i dont think a joint could be damaged by a faulty adapter or just something i dont know...

[jefe]

If it's acting the same with battery, then your adapter is probably fine.. try the adapter on another pedal just to make sure.

My guess is you've got a bad solder joint (or two, or three..) somewhere, since you've already discovered other bad solder joints. Or you could have a reversed or fried component. Can you take some close-up pictures and post them?

[vendettav]

ahh I don't know if I'll be able to get pics...
the thing is it was working for days before that... so no reversed components. probably either a faulty joint just revealed itself either something did fry

well the adapter works but i guess its cord is slowly dying....

anyways I'll go thru the whole schematic again and see if I can find any faulty joints.. will redo the suspicious ones as well

[vendettav]

Ok i checked it and re-did some soldering.. still doesnt work...
what shall I do? I'll get the voltages again as soon as possible but here's a thing I checked: with a square waveform generator on my DMM, I had my output connected and was probing components and I had the saw sound past C9 (to the LEDs, etc. and output) but it wouldn't make any sound before the cap like the positive leg (and anywhere else on the schematic. it would get some buzzing or somethign at some points but it wasn't the audio signal really). is it the way it has to work??

[vendettav]

update sorry for the double post and whatnot

anyways I checked the voltages:

1. 8.42
2. 7.68
3. 4.4
4. 0
5. 8.8
6. 4.4
7. 8.4
8. 9

ok now my adapter outputs 9.6v or something
still aint the pins 5 and 7 wrong as well as 2nd or something? help guys I really need some support
