Thanks OzMike, but the warning's not really needed. I've always been a bit of a risk taker, consequently I've seen the magic smoke on more than one occasion. Quite a few people running other T-amps at this high a voltage AFAIK (although other boards may have a diode incorporated already), and I like to leave out as many components as I can so I may just go for it.

Actually the datasheet <i>I</i> got from the Tripath site says 14.0V max operating and an absolute maximum of 16V??

The chip does have a thermal shutdown on it, but the word is that at close to max voltage/temperatures, it will have a shorter life. I found just a few tenths of a volt between 13.5 and 14v really make a dramatic difference on running temperature. If you have access to one, a point-and-shoot infrared thermometer is a great tool for checking this

Be sure to put a heat sink on the chip if you're running close to the max voltage.

The board I bought for 13 is the sureelectronics one.

The board in the title of the thread does indeed cost $50-odd to ship. There are 2 offers I've seen, one in USD which works out to about 30 total, and one in UKP which works out to about 40.
