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) | 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. | ||
