INTRODUCTION

PA35CX are possible with the EK33 PC board. Mounting holes

are provided and the provision for standard banana jacks simpli-

fies 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.

several component locations have specific functions and will

usually be necessary:
