I recently purchased a Total Bithead (little over a month ago) and noticed a bit of noise in the higher frequencies (about 8KHz+) but I tried to shrug it off as I was getting pretty amazing sound for $150. But it eventually came to the point that I could no longer bear battery power (this noise began to show at all frequencies). Today I gave the batteries one last attempt, as I flicked the switch however, nothing happened. I flipped my Bithead over (it was sitting on the rubber door) and noticed white substance encrusted around the edge of the door. Opening it revealed several exploded batteries leaking acid. The amp can no longer be powered off battery power. I just sent HeadRoom an email so we'll see what they say.
However, I'm curious if this is a common issue? I've read a few posts here mentioning buying second hand units that HeadRoom repaired of battery leakage issues. Does anyone have anything that can help me?
And now you know why you deal with a company like Headroom. They are first class all the way. And you're right, they do ROCK!

Signature Garage Sale!

more info. At the moment I'm only offering these within
Australia to keep payment and postage simple.
I had exaclty the same problem as above. I called and was offered a new one, but I decided to see what would happen. I cleaned the contacts and replaced the batteries with new ones and I have had no probs since. I'm wondering if maybe it happens only to the first set, as the chipset in the Bithead breaks in...
but what do I know..
As we know,

That is to say
We know there are some things
We do not know.
