Kingslayer IC - issues

[jimilee]

Also I confirmed with Rej on his klon, if you're running buffered out you have to have the stomp connected, BUT If your voltages aren't right, still a bridge somewhere. Does the IC still get hot? Etched boards can be tricky sometimes.

You still need to figure out why you don't have -9V at pin 5 of the charge pump. Time to use the continuity tester on your multimeter and make sure things that are supposed to be connected actually are. It's also possible you fried the charge pump at some point.

MIght help to see the other side of the board as well.

I'm at work Jon.  I'll test continuity and post a pic later tonight

I'm a fool sometimes.  I went home to take a picture of the top of the board and it hit me. I didn't do a good enough job on hand drilling the copper.  (I made the mistake of taping off the copper on top, still can't figure out what possessed me to do so!) I figured I'd just remove the copper around each hole.  It took forever.  Watched at least a couple hours of Olympics while doing so.  I was very careful to remove enough copper and place the components in a way that avoided contact with the copper on top.  Obviously the components must have shifted or were making contact from the start.  It would explain why I had signal to start with and not now.  Might explain why I got negative voltage on PIN 5 briefly and then not.  In my head, this complicates things to the point that I should abort, buy a prefabbed Kingslayer and start over.  Don't have the heart to etch another one right now.  At least I can salvage the pots, toggles, ICs and diodes.  At the risk of embarrassing myself I'll post the pic of the top.

DDAAAAMMMNNN!!! I have never ever seen that before!

Yikes!   

Thanks for posting the pic!

That's okay... before regulation almost a 700vdc differential. My first tube project, quite a few years ago.
