Ultra Class A Superdrive Power Amp

[flibbergibbin]

I finished my first project the Utility Boost. Actually it's two daisy chained together. I was wondering if I could use the two Utility Boosts as a preamp, as it says on Circuit Snippets, for the Ultra Class A Superdrive Power Amp? I have two little 8 Ohm speakers that are 0.5 watts a piece and was wondering if the audio transformer recommended would work with the all the above taken into consideration? I'm posting a link to the radioshack page with the information on this audio transformer. If it wouldn't work would someone be so kind to suggest one that would? Thanks in advance.

Here's the Circuit Snippet Page. The Ultra Class A Superdrive Power Amp is almost at the bottom of the page. Thanks again everyone.

Okay, I got all the above figured out now I need some help with going from a 9 volt power supply to 18 volts. How would I wire this up? My first thought was just run both +'s of the two 9 volt battery clips to the now 9 volt spot on the board and both grounds to the input jack's ring lug. Is that right?

No, you need the two batteries in series. Connect the black lead of one clip to your grounding point. Connect the red lead to the black lead of the other clip. Connect the red lead of the second clip to +ve on the board.

Thank you so very much.
