My RA-1 Clone on PCB is going well. However, this AM when I connected everything I noticed one of the 9V batteries was extremely hot.

I assume this is not good as it could become very messy.

Any help with this issue would be greatly appreciated from my wife and kids.

I understand that at least according to one head-fi'er suggestion to follow the Dip-16 diagram and wire the 9V batteries like this.

Here's what it looks like upclose and personal.

Do I have the batteries connected properly in series?
Could it be that I need to use a DPDT switch instead of the SPST?

Here's a picture of the PCB.

Yeah, you'll need a DPDT for this... one pole switching V+ and the other switching V-. Crude ASCII dwg:

Code:

Yup, simple fix and you called it...DPDT is in order.

Currently when you flip the switch it shorts the batteries. Nice.

Good luck, im sure you'll have it in working order shortly!
