Help! Circuit making white noise ROG May Queen

[A Paz]

Hello, I am trying to build a ROG May Queen and there is a ton of white noise at the collector of Q2. The guitar signal also sounds 'choked' like there isn't enough voltage, but all of the voltage measure as they should according to runoffgroove.
I have actually built it twice with the same result because I thought I messed something up the first time.

The first build used the vero layout here: https://paulinthelab.blogspot.com/2017/ ... ly-by.html
the second, is the ROG perf layout.

I have breadboarded this circuit a few times and had no issues. I have checked everything I can think of, solder joints, voltages, component values/orientations, and I have no Idea. Because both builds have the same issue, could it be my parts? or am I just an idiot? I have no idea at this point.

Is there a common issue that can cause white noise? I'm at a loss.

Thanks for your help, I'll post pictures later if anyone thinks that will help.

Welcome to the forum!

If you've breadboarded it several times without trouble, then the circuit design should be OK. The schematics for ROG and Paul In the Lab versions are identical, except the value of the bypass cap at the trimmer for Q3, and ROG has a volume pot.

Yes, photos would be helpful.

Are you powering it the same way you powered the breadboard? A 9V battery won't add any noise, while some power supplies can.

<edit> Looking at the vero layout, it calls for 8 trace cuts, 6 of them are easily visible but two are hidden - did you make the cuts at C8 (under R6) and D7 (under C3)?

Soo it turns out that my 2N5088s have a different pinout than the ones the dude who made the layout had. I thought it was Q2 until I desoldered and socketed all the transistors. I flipped and switched them out until it worked. I guess that my Q1 was backwards. I feel dumb; I didn't realize that the same transistors could have multiple pinouts.

Edit: I got both of them working. So I guess it only took a few hours to learn a simple lesson.

We've all been there. Congratulations on getting both of them working!

We've all been there.

An old guy I used to work with always said that if you never made any mistakes it was because you never did anything.
