Cigar Box Amplifier grounding and power options

[Dave]

OK, I have a serious question this time :-)

I am building another cigar box AMPLIFIER, using a 2.5W Artec amp circuit, an Artec QDD2 Quadra Distortion Driver circuit (both from site sponsor C.B. Gitty), and possibly a 9v slapback delay circuit of some sort (yet to be determined).

See my diagrams below (and I apologize in advance for my lack of electronics knowledge and poor schematic drawing skills).

I would ideally like to use a single 9V battery to power everything, and have everything on a common ground, as in drawing "A". I have a feeling that this is too easy and simplistic to actually work. Would it?

If not, would I have to use three different 9V batteries, as in drawing "B"? And, will this work as drawn, using a common ground bus?

The $64,000 question: if neither of these layouts would work, then what am I doing wrong, and how can I do it correctly and efficiently?

Remember, I have the mind of a child, so please respond accordingly.

Both will work fine but you'll get better economy from 6 x 1.5v Cylindrical batteries in series

Interesting; thanks for the info. Looks like I will give the top drawing a try, and hope for the best. Everyone else agree?

In case anyone is wondering, I received some fairly complete responses on another forum (TDPRI), and eventually wound up with this diagram. The only addition to this schematic would be an on/off switch for the delay unit.

Right on; I have actually already decided to use three batteries in parallel.
