My first Vero Layout. Is all right?

[intergalatico]

Hello Folks,

I just finished a vero layout of the BYOC Octave Fuzz.

Would some nice soul take a time and look if is all right with it?



Thank you so much!!!

Cheers

Oh, almost forget. Here is the schematic:

Cheers!

i just looked it over, no promises cuz my vision sucks, but yeah baby, it looks hip to me, nice layout too. my first couple hundred sucked give it a shot!

[intergalatico]

I didn't make it to work... I think I mess the things up on the transformer.

Can somebody help me on that? Wich is the pins 1, 2, 3, 4, 5 and 6 of the TM022?



I really apreciate it!

Thank you!

you're gonna have to figure that out yourself, but it's fairly easy.
take your multi meter and start reading impedances. you can probably set it to diode check so it "beeps" on continuity.

you will find two wires that are connected and beep. that will be your primary. 1 and 2 don't really matter much i wouldn't think. more on that in a minute.
on a resistance scale, you'll probably see something between 40 and 200 ohms. just a guestimate, i haven't built this project.
once ya know what your primary is, read the secondary. two of the wires will read the full resistance of the secondary, and one of the three wires will read half the resistance. that will be your center tap.

now you can hook it up as required. if it squeals like a banshee, reverse either the primary wires or the secondarys, as that squeal comes from the input and output being out of phase with each other.

you should be good to go. keep at it, you'll get it right. takes us all a while to discover things and learn.

Should help you suss it pretty quick

As Jimi says always good to learn and there's nothing like the practical experience of doing it yourself and I've learnt something here so thank you sirs!

[intergalatico]

Thank you guys!

But I think I didn't expressed myself clear. I want to know on the Schematic which one is the pin 1. I had already with the help from the data sheet figured out the pins on the transformer itself.

Is just that the pin 1 and 3 on the Primary can either goes on the top side of the schematic or on the bottom.

Or I am thinking wrong?

I hope you guys understand what I mean and could help me!

Thank you!!!

[intergalatico]

I did like this and is not working:



Maybe should be like this:



And here is the info from data sheet:



Thank you!

[intergalatico]

I just change like the 2. picture and still not working... I am really frustrate 

I get sound from my guitar but no effect... some ideas?

Thank you!

It really doesn't matter which is pin1 & pin3 (they are fully interchangeable)..

Anyway, your vero layout makes clear which pin is No1 so, if your transformer is O.K., maybe you've also connected pin5 to GND..
(haven't you bend over or cut pin5..??)

[duck_arse]

the transformer frame holding the laminations together has two lugs sticking out, for mechanical support/rigidity. did you solder them to your board, and if so, are they connecting two tracks that shouldn't be connecting?

[I can see this one, antonis.]

[intergalatico]

The pin 5 I bend it and is not touching anything. The frames are also bended and didn't touch anything as well.

Maybe I am wiring the pots in a wrong way? I will make some pics how I wire it.

Thank you guys!

[pinkjimiphoton]

just for shitz n grins, try reversing pins 1 and 3 on your pots. it is wicked common for them to get wired backwards, so ya turn it up but it's really backwards.

[Cozybuilder]

If you post clear photos of the board, both sides, it would help.

[pinkjimiphoton]

voltages to ground too will help. just put your meter on dc volts, hook your black lead to ground and read the transistor's voltages.

curious, did you remember to ground the input and output jacks, and the pot casings?

[intergalatico]

Thank you guys!

Unfortunately I don't have time this weekend but I will come back on Monday with the updates.

Can someone check on my first pic if I wire the pots corectly?

Do I have also to ground the pots case besides the 3. Pin?

I will do the voltages reading on Monday.

I really apreciate your help and good to know that I'm not alone on this.

Have a nice weekend!

Cheers

[nocentelli]

Pots are correct.

[pinkjimiphoton]

Do I have also to ground the pots case besides the 3. Pin?

no, you don't have to, but in my experience distortion devices can be kinda unstable and hum/squeal/not work right if the cases are not grounded. ymmv

[intergalatico]

Like I promise, here are the Voltages I am having:

Q1: E=0.36
      B=0.33
      C=0.18

Q2: C=9.15
      B=0.18
      E=2.24

Q3: C=4.76
      B=4.94
      E=1.36

On the transformer is 0V on all Pins... so something is wrong I suppose, but where?

On the 33u capacitor that goes to the secondary side of the transformer I am reading 4.60V on the + pin but 0V on the negative.

Please, help! I am so close to give up or just beginning again from the scratch.

Thank you!

Something with (or around) Q1 is totally wrong..
(maybe some wiring problem or defective BJT..)

P.S.
On-Bypass LED (SW1C) should be reversed in schematic..
