Avalon Design VT-747sp for sale. This rack mount unit was part of the Scissor Sisters studio here in NYC. Search our site for other items we purchased from them. This unit is defective and requires repair. We normally do our own repairs here, but Avalon is still in business and they know these inside and out, so we're selling it as is for the buyer to ship to Avalon directly. Either that or, if it doesn't sell, we'll send it to Avalon when we get around to it. See the photos here - the bottom ones show some burned components on the circuit board.
