New power supply for the Quad 405 1 and 2
A new double power supply for the Quad 405 1 or 2 and DIY projects.
We developed a new supply with an integrated DC protection for your speakers. It is based on the circuit in the Quad 306, 606, 707, 909 and 520f range. It uses the so called virtual earth technique.
Integrated DC protection for your loudspeakers.
Only one fuse in the AC circuit, integrated in the power supply.
You can remove the clamp circuit from the 405 modules or the chassis.
Also you can remove and short circuit those non linear fuses in the DC circuits of the 405 modules. These two measures are strongly advised!
Symetrical clipping due to PSU voltage offset, like in the 606 range.
No transformer needed with a central tap, simple cable layout.
Price information will follow soon. The production unit may differ in detailing, also there will be a choice in capacitors, but the minium will be 10.000uF.
Update 18 december: The Dual Mono power supply with 4x15000µF BHC Aerovox and Loudspeaker-protection is available in the Webshop now. Click here.
