12 VDC 3A Power Adapter
can this power and amp and charge an ipod?
can this power supply be used to power the Dayton Audio DTA-2 Class T Digital Audio Amplifier Module as well as run power to an ipod dock to charge an ipod or iphone? perhaps with some extra parts?
The DTA-2 requires a 12 volt power supply that gives at least 2 amps. This will fit the bill nicely to power that amp.As for an iPod dock, it really depends on the dock. Most docks are designed to get power over USB, which is 5 volts at up to 1 amp.So, there are a few ways to do this.1-The easy way: Buy an iPod dock intended for use in an automobile. These are made to run off of 11-14 volts, so your 12 volt supply will work great. These can be found with a bit of Googling. Then you can wire the 12v power source right to the dock's power cord.2-The DIY (manly) way: Use a voltage regulator to change your 12v into 5v. I have linked the proper regulator below. Look up the 7805 datasheet for a proper circuit. This will require a bit of soldering, the regulator, a heatsink and a couple capacitors. This will allow you to provide 5v power to a regular USB powered iPod dock.3-The h4xx0r way: You could use an existing 12v->5v transformer, like those intended to allow people to charge USB devices in cars. I have one linked below. Wire your 12v power to the end that would plug into the cigarette lighter, solder securely. Then you have 2 available USB ports on the other end that can provide adequate 5v power to any USB devices that may need it, including a regular USB powered iPod dock.Whatever you decide to do, have fun and be safe!

Will this fit the Lepai TriPath amp? It seems to have more current
This will work to power the Lepai amp. Since this is 12V at 3A it provide 50% more power than the Lepai's included 12V at 2A supply. (36watts rather than 24 Watts)However, I cannot confirm that the barrel connector on the two power supplies is the same.Although, there is nothing stopping you from taking the barrel connector off of the included supply and attaching it to this one if need be. Cut, strip, twist, solder, tape, TA-DA!
