Digital Supply


The Digital supply is a low noise, low impedance, ultra-capacitor based power supply. It features a large capacitor bank of 2 x 310 Farads. The charging process is a seamless, microprocessor-controlled process with progress tracking graphics on the ZAP display.


The ZAP provides a very clean reference power supply needed for the VOX. It is made using discrete regulation and can be manually changed in case the ZAP is used independently.

Analog Supplies
