INTRODUCTION
TYPICAL COMPONENT FUNCTIONS
Fast, easy breadboarding of circuits using the PA75CX or
PA35CX are possible with the EK33 PC board. Mounting holes
are provided and the provision for standard banana jacks simplifies connection and testing. Components are labeled on both
sides of the board for ease in probing. This kit is not suitable
for PA75CC, PA75CD, PA35CC or PA35CD.
A multitude of circuit configurations are possible, so only
several component locations have specific functions and will
usually be necessary:

FUNCTION
Power Supply bypasses MUST be used
for each amplifier. Usually ceramic types of
.01µF to 1.0µF and 10µF of capacitance
per ampere of output current.
Feedback resistors
The following locations should be jumpered unless used
otherwise (their most common function is listed).
Output amp a to input amp b
-Vs
Connects paralleling output a to output b
Connects feedback for amp a
The following locations should be left open unless used otherwise
(their most common anticipated function is listed).
J1, J7
Connects -Vs to ground reference
The function of all other components is up to the designer's
circuit needs.
