Hi
First posting, maybe dumb, but...
I just got my t-amp. It has a dc output but I dont know if + or- is in the centre of the contact. Also it says you can use a 14 volt transformer, though it says 12 volt in the back. Thankful for help.

Well I am kind of new, but it says dc 12 volts under the connection hole on the back. The the question is what is + and - so I dont ruine the thing.
An externally hosted image should be here but it was not working when we last tested it.
This amp is DC, the cheaper one I think is AC, this one is clearly marked.
A 12V car battery is actually 13.8V, so it should accept 14V.
Note a 14V AC transformer when rectified does not produce 14V DC.

Ok thanks. If your wrong I will hunt you down no matter what continent your on...
It says in the small manual that you can use 14 volt, but maybe safest not to try it. Thanks again. Time to connect.

As the man says.........
DC..DC...DC It is recomended for 13.2V maximum.
Do NOT put AC through it, it WILL fry!!!!
Cousin Lostcause is quite correct. DC ONLY!
I had the little SMPS that comes with the Super-T tested. It does very well. Good regulation, low noise, holds 11.98V at its rated 3A. Handles short circuits like a champ.
Maybe I can talk the Sonic guys into selling that power supply for the original Sonic Impact, too.

Hi,
I'm only going on bits and pieces I've read about running
T-amps off car batteries, and I'm only familiar with the two
amps that parts express sell.
I'll stick by the assertion : anything designed to run off a car
battery will accept 14V dc.( Or it would be in big trouble.)

A logical assumption, but not totally accurate in this case. The T-Amp is NOT designed to run off a car battery, or to be used in a car. It is designed to be powered by 12V. Tripath state 13.2V as OPERATING CONDITION max, But 16V as absolute max. The problem is cooling.
Yes, it will run off 14V, but it is not really good for the chip as it lacks proper cooling in the Sonic amps. 14V won't kill it right away, but a number of DIYers have had chip failure at 14V. It can be done, but proper cooling needs to be implemented. The chip will work just fine at 12-13V, so why push it?
