INTRODUCTION

ing and grounding to breadboard eight pin TO-3 packages or

the MO-127 package with 0.060" pins. This kit is not intended

as an alternate for kits dedicated to specific amplifiers. See

www.Cirrus.com for availability of dedicated kits.

Holes are provided to mount standard banana and BNC con-

nectors for I/O. See the Apex Precision Power Accessories

Information data sheet for a selection of flat-back heatsinks

and thermal washers for these packages.

can be used if desired. If the EK09 is to be used as an MO-127

platform only, HS18 rated at 1° C/W is a cost effective alterna-

tive to HS11 if internal power dissipation permits. Lower cost

alternatives for two package TO-3 applications are HS02, HS01,

and HS09. For single package TO-3 applications the HS13 is

also suitable. The six chip capacitors provided can be used as

the critical first step in power supply bypass for dual supplies

for all three sockets. These capacitors are rated at 200V.

BEFORE YOU GET STARTED

• Attempt to visualize the finished circuit mechanically and in

• Use proper ESD precautions.

• Verify heatsink is adequate

• Use thermal grease or A pex Precision Power thermal washer.

• Do not make or break any connection on a hot circuit.

• Start with lowest rated voltages.

• Checking for oscillations with an oscilloscope is a must.

EK09U

This kit provides a solid mechanical platform with good shield-

Construction will involve surface mounting and 3D techniques.

Note that HS11 is compatible with EK09 and all three sockets

terms of where the high currents flow.

ponent side, where all the support components will determine

circuit function and will be inside the finished box. The other

side of this board is hereby dubbed the amplifier side.

one of these techniques: 1) Place cage jacks in holes, cover

with one of the 6" copper sides, flip over and solder, or 2) place

cage jacks on pins of the amplifier, insert and solder. If done

carefully, technique 2 can be used for the MO-127 package

with 0.040" leads.

on end works fine) and solder the two together. Repeat for

the other two sides, and finally solder the two pairs together.

will be floating unless you tie them down.

mediate area of the socket(s) to the ground connector of the

power supply(ies) is good construction practice. If the circuit

is not a bridge, run this same size wire from the socket area

to the output return connector. This will avoid high currents in

the ground plane which may destroy signal integrity or even

an amplifier. This is a good time to think about star grounding

where each ground connection has a dedicated path to the

center of the star such that currents in any path are not capable

of inducing voltage in any other path.
