Did you have a load on it when you measured ? Remember that cheap power supplies put out "something vaguely like 12 volts if you draw exactly the right amount of current" while good power supplies put out pretty much exactly 12 volts.

12 volt car / motorcycle batteries, on the other hand, put out 13.8 volts +/- a volt or so depending on whether or not you are charging.

Yes. It's supposedly a universal adapter, so it may have something to do with the switch. It's quite old, and now that I think about it I used it with my first discman, which stopped working. And then my second one, which also stopped working. I forgot all about those until now.

I checked my Radioshack wall wart and it was outputing 15.3V instead of the 12V advertised. I knew i thought my amp was getting a lot hotter than usual.

Firstly, a BIG thank you to those who started this thread. I usually lurk on a lot of BBS's but this was the first place I heard about the T-amp. I would've expected the Home Theater Forum to have alerted me of its existence - I guess they're too busy fawning over SVS there.

Next, more of a buying guide for International customers. Thinkgeek keeps the T-amp, but the shipping cost to South Africa was 1.5 times the cost of the T-amp. I eventually ended up getting it from Parts Express. They have a $100 minimum for international orders so I had to get 3 T-amps + a few accessories (a friend took 1 and my big brother is getting a cool new birthday present soon). Now PE have changed to a weird credit card policy. You now have to verify your bank details (which means faxing your previous statement to them) or you have to use Paypal( not available for SA) or direct bank transfer/ money order. Even though I was a returning customer I had to comply. Parcel arrived at my Post office 12 days after shipping, which is pretty fast.

I am really pleased with this product. It is ridiculously tiny! For anyone who's worried its measly 6 watts in my 13' by 15' room make my M22's go really loud. In fact at my normal listening levels I don't turn the volume past 33%. I am running it with a 13.8V regulated power supply. The t-amp reveals a whole lot of detail (maybe it was there before and I didn't notice).

My Pioneer receiver has pre-outs for all channels so I can use it as a pre-amp and bring my subwoofer into play. Mostly I just run straight from my dvd player to the T-amp.

Finally, kudos to axiom's customer service. You can imagine my horror when I was showing off my system to a few friends and then got this weird sparking sound from 1 of my m22's while playing Santana's Soul Sacrifice. Put on a 200-20 Hz test tone and it turned into a constant whine at certain frequencies. Call up axiom and Brent? told me to tighten the woofers down with a hex driver ( allen key ). Problem sorted.

OK, I've heard enough. It's time I bought a few of these puppies!

Anyone know of a power supply that might have two or three outputs without getting into industrial test-bench solutions that would cost what a real tube amp costs?

Sears Die-Hard with a trickle charger? or 3 Pyramid 13.8V/3A power supplies for ~$20 each?

Here's a site with the Pyramid PS7KX regulated power supply (13.8V/5A) for $22.95:

Here's an ebay site where you can buy-it-now for $19 each

I've been away on vacation, but just saw your post. Here is what I'm using. It doesn't quite have the specs of the power supply 2x6 linked to, but it is decent, and seems to be doing an excellent job for me.

Parts Express PS

It's also a little less expensive (that Ebay guy wanted $20 to ship that Pyramid PS!). And if, like me, you don't really want to solder anything, you'll see a detachable mini plug kit on the same page that makes connecting it a breeze.

Good luck!

Just thought I would post this article for those who have not yet read it. It's a more thorough walk-through of the basic chassis mods. Very much a beginner "tweaking-audiophile" article.

Re-boxing your T-Amp

Well, I finally bought one of those Pyramid PS7KX power suppies.
Have not yet hooked it up, but now I'm thinking of getting out the soldering gun and trying some of these other mods as well.
Hmmm...
