Rega's new, revamped TT-PSU incorporates a slick new design and improved circuitry for an even lower noise floor and sweeter sonic offerings than the previous model. If you haven't heard your Rega turntable driven by the TT-PSU Outboard Power Supply, you have not heard it's true capabilities! More than just a power supply, the TT-PSU also allows you to switch between 33RPM and 45RPM with the push of a button. Based on the same power supply from the Rega P9, the TT-PSU is a serious upgrade. This 60hz version works with Planar 3 and RP3 turntables.
