Coil Audio PS6 MK2 is a 7U rack tray with a separate 2U power supply, built to house and power up to six CA-series modules at once, so there is no need to buy separate power for every preamp individually.
One power supply, six modules
The power supply delivers a 6.3V filament voltage at 4A and a regulated 275V B+ voltage at 0.5A, with switchable filament power for 1-3 or 4-6 module configurations. That means you can start with a single CA-70 or CA-286 preamp and expand the system gradually up to a full six channels in one enclosure.
