Pin polarity for T-amp AC adapter?

[Raoul]

I wanted to rig up an AC to DC adapter for my SI T-amp, but the necessary pin polarity isn't marked on the back SI amplifier. Could someone help me out?

Thanks

Use a multimeter to measure the DC outputs, if you get positive, then the polarity matches the multimeter, if you get negative, the polarity is the revers of multimeter.

Thanks for the reply, soongsc. I think I phrased the question poorly. I am looking for what the pin polarity from the adapter should be. I have a regulated supply and need to know whether the pin should be positve or negative. Thanks again for the speedy response.
