So even though you got it working, it may still be damaged if you put the batteries in wrong at some point (which apparently you did). I personally would contact Ray and see what he thinks. If it were me, I would probably send it back to him so he can test it out to make sure everything is working to spec.
Every Tomahawk is very well tested for over 20 minutes before it is shipped, all tests are done using the copper top battery. Here is the very last instruction on how to put the batteries in the Tomahawk.
Look at the battery compartment "back cover", you will see the out line of the 2 AAA batteries silk screened on it. The way you see the out line that is the way they should be inserted into the amp.
OK, here is the other way which you can follow, the battery that is closer to the center of the amp, the NEGATIVE polarity should be inserted first into the Tomahawk, this means the positve polarity is facing you when looking at the amp from the back. The other battery, which is closer to the wall of the Tomahawk, extreem right, when looking at the amp with the back end facing you, The POSITIVE pole should be inserted first, this means the negative side of this battery is facing you, when looking at the amp from the back side. One thing important you have to do is make sure when installing the back plate or panel, that it completly rests against the body of the amp & that both tumb nuts are fully bottomed & no space or gap is between the back plate & the chassis. This will insure a good contact between the batteries & thier contacts.
I had one shipped to me with two thumb nuts not screwed all the way & the battery made poor contact with the batteries spring contacts.
