Some answers about the voltage issuedoobooloo,
I asked a friend to take a look at these pictures to see if it would be easy to configure the power supply to 110v-120v (I'm technically challenged). Here's his first reply:
"In one of the photos showing the power transformer, you can see a label on the transformer. It appears to have two windings on one side and three windings, two of which are center-tapped, on the other side. Since the center-tapped windings would normally be on the secondary, then other two windings comprise the primary. A transformer with dual primary windings can normally be hooked up for two voltages. Doobooloo says it's designed for 220V, so the windings could be reconfigured to run at 110V. Since 120V is the North American standard, the amp's internal voltages may be about 10% too high, possibly pushing the limits of the regulators in the power supply. Unfortunately, they don't show a schematic for the power supply.
Reconfiguring the transformer for 110V operation may be a challenge in the assembled units if the transformer wires have been clipped short. If the transformer has lugs on it, it may be easy. It shouldn't be a problem if you buy the kit version.
Perhaps doobooloo can request that they be assembled for 110V and also could ask the manufacturer if the transformer has dual primary windings."
He then found a close-up picture of the power transformer from the website, and sent me this reply:
"Here's a photo where you can read the text on the transformer. It has dual 110V primary windings as I guessed. There's still the question of whether the wires are clipped off once they set the unit up for 220V"
So please check to see if the seller can convert it to 110V or if the wires are long enough to reach the other side of the transformer, or if the transformer has lugs on it (I suppose that means wires are not hot-wired into the transformer, but somehow connected to the transformer by screws or lugs.)
