I have 10MU of Dotcom-format modules in my side cabinet that consist of a Moon Modular M569 Quad Sequential Voltage Source and a Synthesizers.com Q109 Envelope Generator, and a Q115 Reverb.

I mounted the reverb tank vertically on the cabinet side to minimize the coupling from the nearby power transformer.  This orientation significantly minimized hum.

Power

I use a MOTM-990 power distribution board and build MOTM-to-Dotcom power cable.  Both the M569 and Q115 are +/- 15 volt modules that use the 4 pin MOTM connector.  The Q109 uses the 6 pin MOTM connector for the additional +5 volts.
