Problem with integrating little gem MKII into talkbox

Hi all, I'm trying to build a talkbox that runs with it's own internal amp like the Rocktron Banshee. To power the internal horn driver, I built a Little Gem MKII. However, I am having a very difficult time in getting this thing working because I cant figure out what to connect and where.  I used the instructions off http://www.blamepro.com/talkboxG.htm to wire the plain talkbox circuit without the amp, and I got it to work. But the problem is with integrating the amp http://www.runoffgroove.com/littlegem.html (Lower one on page) into the rest. I have no idea where I'm supposed to connect the inputs, outputs, ground, and the power source (9volt battery) because the amp circuit and the plain talkbox circuit connections seem to interfere with eachother somehow. I'd really appreciate it if someone could show me how to wire the amp and the talkbox circuit together.

  Have you checked out GGG?
  http://www.blamepro.com/talkboxG.htm to wire the plain talkbox circuit without the amp, and I got it to work.
  I had trouble finding / envisioning a wiring diagram or schematic from that text.
  Basic block diagram:
Part 1 guitar > amp > horn > tube > mouth with adjacent microphone
Part 2 mic cable > 'amp' > speaker.
  'amp' can be PA.
  The guitar plays the horn through the amp, the resulting soundwaves are injected into shape-shifting mouth, exiting in proximity to a live microphone.
  Generally speaking the signal is usually modified in some way between guitar and amp, such as distortion and voicing.
  When debugging an amplifier > speaker system, which the talk box is, first test would be speaker and cable which could be tested with another amp [but I just use the battery click test], and then the amplifier [which can be tested briefly with the confirmed working speaker/amp continuity].
  A common option is signal routing [the text probably explains/includes this], such as splitting signal, left side to TB, Right side to guitar amp.
Convention creates following, following creates convention.
