AM1002 Power Supply

ARP 1002 Module

Overview This is the power supply module for my ARP 2500 Racks, replicating the look and feel of the ARP 1002 module. My module contains a +/-15V power supply for the rack which is an Oakley Sound PSU mounted on 40mm M3 stand offs. The 15V power is connected to an internal distribution board, and the PSU is supplied by an external 16VAC power supply.

The panel has front mounted red LED’s (one for each power rail), 2A fuse holders and a power switch. A separate +12V power supply is mounted on each AM2500 to power the LED’s and lamps and the 1050 and 1027 have local +5V power regulators..

There are 10x 3.5mm jack sockets mounted at the base of the front panel, these are:

  • x5 Multiples
  • Pitch
  • Gate
  • Trigger
  • 5V Gate
  • Velocity

Build History The first 1002 power supply was built in August 2015 and used in the prototype AM2500 10U tolex rack cabinet.

19″ Rack Power When I moved the 2500 modules into Oak Cabinets I wanted to use the 5th module space that was “wasted” with the 1002 PSU module. The 6U cabinets have a 1U space below the modules which I have fitted a 19″ Schroff aluminium rack (20860-601) into the space. It contains a complete 15V power supply with toridial transformer, with front facing 8-pin keyboard connector and various jack sockets, and rear facing 15V power connector and keyboard CV’s, gate and triggers.
