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:

Code:

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

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