         NEA ARP Power Supply Installation Instructions 
                              
Thank you for purchasing an NEA Linear Regulated PSU unit for ARP synthesizers.  This power 

supply has 3 adjustable outputs.  The outputs can be adjusted as follows: 

R9 = +5V adjust 

R57  = 15V adjust 

R82=+15 adjust 

 

There are 5 output pins from the power supply.  The pins in the grouping of two (out and +out) 

have 5V across them.  This supply can be used for a digital supply or as an LED supply for 

synthesizers with lighted LED sliders.   

The grouping of three output pins (out, com, +out) corresponds to V, GROUND, and +V. 

For standard 120V operation, connect the white wire (neutral) to pin 4, and the black wire to pin 1. 

Do not connect to pin 5.   

See the diagram below for other AC wiring schemes.   




                                                                                                
 

To install this PSU in an Odyssey, the old PSU must be removed to make room for the new 

one.  The holes for the old PSU can be filled with either the old nuts and bolts, or can be left 

empty.  The NEA PSU mounts in the base of the Odyssey.  In early Odysseys, the base is 

vinyl and detachable, and on newer units, the base is an integral part of the case.   To make 

the 4 mounting holes needed to mount the PSU, use an awl, or other sharp instrument to 

mark started holes where you are going to drill.  This is easily done by placing the PSU 

where it is going to be mounted, and while firmly holding the assembly in place, poking an 

awl through the PSU base mounting holes to mark your starter holes.  The PSU ships with 

the screws attached to the base in the manner that they are to be mounted to the base of the 

Odyssey.  The power switch can be wired in the same manner as on the original ARP PSU. 

Remember to leave enough slack in the PSU input and output wires to make servicing 

possible.  Spade jacks (as used in speaker systems) can be used for ease of disconnection. 

Always be sure that the PSU is going to fit in the spot you are mounting it.  Take care to 

mount the PSU in a manner where it doesn't make unwanted contact with PCBs or pins 

from the power switch.  Take your time when doing this installation.  Thanks for your 

purchase!
