Tomahawk problem - Page 2

post #16 of 22
It says right in the Tomahawk owner's manual that inserting the batteries the wrong way will result in damaging the Tomahawk's circuit. So it is very likely you did some damage.

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.

Good luck.

Thanks for the replies, guys. I emailed Ray as soon as I realised it wasn't switching on.

Further to my last post, it stopped working again whenever I moved it slightly. The problem was what wolfB said it was - the contacts weren't touching properly, even when screwed in tightly. I've made it work again by using some folded-up kitchen foil to create an artificial battery nipple.

I cannot hear anything wrong with the sound but, as you said, I did switch the batteries around at first when it wasn't working. Is it possible that I've damaged it in a way that isn't causing any clearly audible effect?

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.
Thanks.

Hi John...
You did not damaged the amp at all if it works. Make sure the back panel is clean & has no oil contamination from touching it. Make sure the batteries bottom poles "the negative pole" are sticking out beyond the outside casing of the batteries, also make sure that the batteries are touching the NON black anodized area of the back panel.

Thanks for the reply, Ray. Believe me, I'm screwing it in as tightly as possible. Doesn't matter, though, as I've got it working using an artificial battery nipple made from kitchen foil.

maybe coppertops in the uk are different from other countries? I know they have different plants around the world to serve different markets. Sanyo Eneloops are guaranteed to work fine in the tomahawk (non-defective one that is) and they are all manufactured in Japan so should be the same dimension wherever you buy it in the world.
