possible with the EK33 PC board. Mounting holes are provided

and the provision for standard banana jacks simpliﬁes con-

nection and testing. Components are labeled on both sides

of the board for ease in probing. This kit is not suitable for

PA75CC or PA75CD. A multitude of circuit conﬁgurations are

possible, so only several component locations have speciﬁc

functions and will usually be necessary.

cage jacks. These are mounted directly in a print circuit board.

After soldering, the carrier is pulled off the cage jacks. Use

a spacer between the PCB and the heatsink to avoid short

circuits.
