In the 1970s, Tek produced their own '''miniature relays''' in-house that were used in some [[7000-series plug-ins]] such as the [[7A11]], [[7A12]], [[7A13]], [[7A14]], and other equipment.

These relays have a tendency to fail and working spares have become very rare. Some of these relays have symmetrical socket layouts so that they can be installed in both possible 180° rotated positions. | |||
Interestingly, Tek appears to have manufactured replacements based on commercial relays in TO-5 metal can cases soldered to small carrier boards with pins matching the Tek sockets. | Interestingly, Tek appears to have manufactured replacements based on commercial relays in TO-5 metal can cases soldered to small carrier boards with pins matching the Tek sockets. | ||

Possible repair strategies include "micro-surgery" (Ref.1), installing modern miniature gold-contact relays on top of the cut-off base or, if energizing the coil mechanically operates the relay, using a signal source to cycle the relay for a period of time. | Possible repair strategies include "micro-surgery" (Ref.1), installing modern miniature gold-contact relays on top of the cut-off base or, if energizing the coil mechanically operates the relay, using a signal source to cycle the relay for a period of time. | ||
