All Coil Audio Amplifiers are available in two different chassis configurations

The PS6 Rack Tray and Power Supply can hold up to six of our modules. It’s comprised of a 7U Rack Tray and a seperate 2U power supply.

The PS2 Rack and Power Supply combines the modules and power supply into a single 3U case. The PS2 can be ordered with one or two amplifiers factory installed. For mono units, add on modules can be purchased and installed later by Coil Audio.

Both configurations feature a 'soft-start'/standby of the modules by allowing you to switch on the Filament and B+ voltages separately.
