Anyone who built the Wrecking Ball from C2C Electronics ?

Crap, I thought I had those in the BOM, looks like I don't. The holes are sized for M3 hardware, standoff should be 10mm long (not including threaded section).

Perfect, thanks!

Hi All, long time lurker, first time poster.
Nice to be a member of this great forum.

I started to build this pedal, I built a few solid state & tube pedals in the past and also three tube amplifiers.
This is the first time I build a project with a SMPS voltage charge pump.

Usually when I start to build a tube amplifier/pedal, first thing I do I check the power transformer output after rectification.
So for this project I soldered all the power supply components and checked voltages.
The HV on C14(9.2 VDC) is almost the same as the input(8.8 VDC).

So excuse my SMPS nooby question.
Is this normal for SMPS power supply without load not to present the HV or there is something faulty?
Will it work when all the components of the pedal are soldered?

Any help will be much appreciated.

Cheers.

That is not normal, there is something wrong with your SMPS. Make sure your NE555 is installed and double check the orientation, also check the orientation of your IRF470 and 2N3904. You should still be getting high voltage even with no load on this.

Thank You!
So it's not normal.
I will start debugging.
