Thank you for the referral Lou. There is an aker sales thread here on the TDH

Here is a link to the PTT http://www.thedentedhelmet.com/showthread.php/35890-FS-Push-To-Talk-(PTT)-Cables-for-Aker-Voice-Amps
I have sold an aker amp to TK409 and he is supposed to be updating his website to recommend the aker amps. He uses an aker now in C-3PO. When i first got started i bought a newton amp based on his website. I hacked it up to fit it into my armor. It lasted one troop before it died. That is what started my search for a better voice amplifier solution. The rest is history. I also sell on Amazon.com. The legion gets the low prices though. I need to keep up the sales volume to keep the volume discount which in turns allows me to keep prices low to the legion. 
As my customers know, there is no comparison between the aker amps and other amps. They are that good. I also keep them in stock all of the time and can usually have them on your doorstep within three days of payment.
Best Regards,
