Warning
To prevent fire or shock hazard, do not 
expose the MultiWave II+ kit to rain or 
moisture. To avoid electrical shock, the 
Power Plant must be unplugged and fully 
discharged before opening.
To prevent electric shock, use a 3 prong, 
grounded type power cable.
Any change or modifications not expressly 
approved in the manual could void your 
warranty.
Safety Instructions
General Instruction:
Read the operating instructions provided 
with your MultiWave II+ kit.
If the Power Plant is powered on with the 
oscillator card inserted backwards, the 
Power Plant will require service from an 
authorized PS Audio dealer.
Retain the operating instructions for later 
use and reference
Completely discharge the Power Plant 
before opening the chassis by unplugging 
the unit for at least 12 hours.
Unplug the Power Plant from the wall outlet 
before changing the fuse or performing any 
upgrade or service.
Do not operate the Power Plant near water. 
Avoid placement near a water reservoir or 
excessive moisture.
When replacement parts are required, be 
sure they are specified by the manufacturer 
to have the same characteristics as the orig-
inal. Unauthorized substitutions may result 
in fire, electric shock, or other hazards.
Do not operate with faulty or frayed power 
cables.
MultiWave II+™ operation:
Any turntable or equipment with AC 
synchronous motors, such as some cooling 
fans should not be used with MultiWave II+ 
unless it is in the sine wave mode.  This 
equipment must be used with sin mode.
We recommend the use of the Sine Wave  
[sin], or TubeWave™ [tub] with any type of 
tube based audio products.
Overview
Read the entire instruction manual 
before starting the installation.
The benefits the Plus upgrade kit will pro-
vide for your MultiWave II equiped power 
plant are:
•  Fine tuning for turntables
•  Clean Sweep
The MultiWave II+ upgrade is a fairly simple 
process. If you have any questions at any 
time, please contact your dealer, distributor 
or PS Audio by e-mail, fax or telephone at 
the numbers listed at the end of the instruc-
tions.
 
The overview steps necessary to install 
MultiWave II+:
Make sure your unit already has been 
upgraded to MultiWave II!  You can-
not install the Plus upgrade without 
MultiWave II installed first.
1.
  Remove the input power cable from the 
rear of the power plant.
2.  
On the P300, remove the bottom cover. 
On the P600/P1200, remove the top 
cover.
3.  
Pull the socketed MW II oscillator board 
out. 
4
.  Replace the microchip on the MultiWave 
II oscillator board.
5. 
Remove display microchip.
6. 
Install new display microchip.
7.  
Insert the oscillator board with its new 
chip, back into the unit.
8.  
Replace the bottom cover or the top 
cover, depending on your model.
9. 
You are done.
Installing the Upgrade
Before beginning the Plus upgrade, you will 
need to do the following:
The Night Before
Unplug the Power Plant the night before (or 
at least several hours before) you plan to do 
the upgrade. Really unplug it! Take out the 
input power cable and take out all the power 
cables connecting to your a/v equipment. By 
letting the Power Plant sit overnight, most of 
the energy stored in the power supply will 
drain away. 
The Day of the Upgrade
Assemble the following tools in your work 
area:
• A clean table to place the Power Plant 
while you are working.
• For the P300 - a #2 Phillips head screw-
driver. For the P600/P1200 - A 7/64” Allen 
wrench.
• A desk lamp, gooseneck lamp or other light 
placed next to the Power Plant so you can 
see what you are doing. 
• The MultiWave II+ Upgrade Kit.
Before opening the Power Plant
• Ensure it is fully unplugged and dis-
charged for at least several hours or 
more.
Disassembly - P300
Turn the P300 upside down, with the feet 
facing up.  Use the screwdriver to take out 
the 10 small screws holding on the bottom 
plate of the P300. Note: You do not need to 
remove the screws holding down the feet to 
the bottom cover of the P300.
After you take off the ten screws from the 
bottom cover, carefully  and  slowly  lift the 
bottom cover straight off. You may notice 
some slight resistance. The oscillator card 
in the P300 is secured by a small gray 
plastic bracket on the inside of the bottom 
cover. Note: some P300’s may not have this 
plastic bracket.
Usually, the oscillator card will stay plugged 
into the P300 main board. Sometimes, the 
oscillator card gets unplugged from the 
main board and instead stays attached to 
the gray plastic support. If this is the case, 
simply remove the card from the support 
and set it aside. 
If your P300 has a fan kit there will be a 
wire connecting the bottom plate to the 
inside of the chassis. Trace the wire back to 
the bottom cir-
cuit board and 
remove the 
 
connector by 
pressing in on 
the side clips 
and gently pull-
ing the connec-
tor out of the 
plug labeled J9. Set the bottom plate aside.
Disassembly - P600/P1200
Keep the P600/P1200 upright so you have 
easy access to the top. Use an Allen wrench 
to remove the Allen screws affixing the top 
cover of the P600/P1200.  Remove the top 
cover and set it aside. 
Removing the old oscillator card - P300
Grab the card by the edges and lift straight 
up to remove. Do not rock the card back 
and forth to remove it! Set it aside.  
NOTE 
THE CARD’S ORIENTATION.  ITS PARTS 
FACE TOWARDS THE FRONT PANEL. 
 
YOU MUST PUT THIS CARD BACK IN 
EXCATLY THE SAME WAY!

lator card to the
