DIP sockets are often problematic as instruments age. | |||
Gold-plated pins carrying low current in gold-plated sockets | |||
are the least problematic. | |||
Higher currents, such as occur in ECL logic, are more problematic. | |||
Tek issued a service note (see below) that describes a transition from the original | |||
C93 socket design to a C95 design which was mechanically too fragile, and then | |||
a transition to an improved version of the C93 socket design. | |||
