The Heavier On One Side Problem
The First Method
Using Various Model VIBRAPOD Isolators
Combinations of Models 1, 2, 3, 4, and 5 VIBRAPOD Isolators will alleviate this problem. Place the Model 3, 4 or 5 VIBRAPOD Isolators under the heaviest area of your component and either the Model 1, 2 or 3 VIBRAPOD Isolators under the lighter areas. This way you can mix and match for the best effect.
The Second Method
Using One Model VIBRAPOD Isolator
You can't just
put VIBRAPOD Isolators along front and back because the weight distribution is so uneven. For the VIBRAPOD Isolators to work their magic the equipment is going to sit offcenter on a new shelf.
Determine the shelf depth.

Slide a hardwood dowel or cut off broom handle under the chassis from the side.

Gently roll the amp front to back over the dowel until you find the center of mass or balancing point.

Mark this point on each side of the chassis.

Measure the distance from that point to the back of the component and to the front.

Multiply the larger dimension by 2.

Add 1 inch or 2.5cm to this number to get the total fronttoback depth of the shelf.
Determine the shelf width.
If the component is symmetrical from side to side then go to the next step.
If not then follow the same instructions for the shelf depth but start with the dowel under the component from the rear sliding the component from side to side to find the center of mass or balancing point.
Finish the project.
Add the weight of the shelf to that of the component.
This gives you the total weight that the VIBRAPOD Isolators will be supporting.
Divide this weight by the following numbers.

(10 for 3/8" Ball) 
When combining VIBRAPOD Isolators and Cones use the weight that an Isolator can support for the combination.

Place the VIBRAPOD Isolators down on the surface where your component will sit Dome side up.
Arrange them symmetrically from front to back and side to side around the perimeter. You don't have to worry about the uneven weight distribution of the component.

Put the shelf on top of the VIBRAPOD Isolators.

Place the component on top of the shelf.
Position it so that its front and side edges are 1/2inch (1.25cm) in from the front and side edges of the shelf.
