warning Vacuum tubes are thermionic devices; They require high temperatures in order to work, which correlates with high power consumption. Tubes that size usually need hundreds of milliamps each - that means your Eurorack system needs to provide LOTS of current. Alternatively, an external power source can be used to offload your PSU.
Frequency Vault can be hard-wired for 5V, 12V or external power supply on order, depending on your needs. warning Please note that vacuum tube modules are generating significant heat that may alter performance of neighbouring temperature sensitive modules.
