I found one cause of the faulty ground. I was using the kludge area to add a stereo mixer. However, one of the kludge terminals connects to C22 (as per the board wiring diagram), and guess which one I ...

Hi, Sven,

Thanks for the reply. Yes, it is lead-free solder, yes it was a bad job. I've gone over all of the solder joins since then and reflowed them; I also clipped back the excess wires.

The ...

looks really cool!

HI, Grumble, Escape Pod,

Your discussion of voltages/resistance from Rn to Ground is exactly why I am trying to get similar information for my non-functional noise toaster.

Hope you don't mind ...

Would appreciate help debugging my unit.

The ground is set by resistors 37 & 42, both 4.7K.

However, my measured resistance from BP to Ground is ~1K, while from BN to ground is ~2K.

I'd ...

Hi,

The wierd sound generator was easy to build, so I thought I'd step up to the noise toaster. Completed the build, but no toast. I'm looking for some help debugging it.

My multimeter suggests ...
