For sale is a USB module from TPA ($50 shipped), Legato 2 (fully built but not tested $50 shipped) and also for sale is a built Placid BP power supply however I've run into trouble with one of the rails. You can read about my problems with it here my profile name is stewart (Problems with LEDs not lighting up and no current adjustment - Placid Dual Power Supply - Twisted Pear Audio Support) One rail works fine, the other is not allowing me to adjust the current. Someone more savvy than I could probably getting it working very easily and cheaply. Asking $20 shipped not including paypal fees.
