RBX - Raw Bias Auxiliary Supply Kit


In Stock
Product Code:


The RBX provides a high-voltage low-impedance raw bias supply when one is not readily available in the amp. It is also useful when the existing bias supply is too low in voltage or too high in impedance to allow proper operation of bias tracking regulators.

RBX assures proper functioning from our London Power SV1, SUS-1, SUS-3 and TBS kits.

PCB assembly makes installation quick and easy.

Kit includes notes with installation tips + schematic and layout diagrams of the kit.

PCB dimension: 3.0 x 2.0", 78 x 50mm

Kit requires assembly. If you would like this kit pre-assembled, add RBX-BLT to have the PCB pre-assembled.
