The RKP is a limited-issue power supply intended to provide the high current demands of Metasonix R and RK series Eurorack modules. It is an 8HP module that accepts DC power from two +12v switchmode power adapters of the “universal” type, provides protection against reverse voltage and overcurrent (5 amps maximum), and has six (6) standard 16-pin Euro power output headers on the rear. The RKP, used with the 5-amp adapters provided, will run any combination of six Metasonix R or RK modules.
The RKP uses high-current adapters because the vacuum tubes in Metasonix modules have filamentary heaters to heat their cathodes to operating temperature (about 650 degrees Celsius). Similar to tungsten-filament lamps, the heaters in tubes have a lower electrical resistance when cold than they do at operating temperature. The power supply must be able to supply this larger “cold inrush” current in order to bring the heater to operating temperature. Usually it requires about 2.0 to 2.5 times the normal operating current, for only a few seconds, to heat the tube properly.
