What was the thinking behind the 'soft' transistor sockets used by
Tektronix in some of the 5000-series 'scopes? I am working on a 5113 / D13
that has these on the storage board. Seems to be a soft white-ish stuff
around the contacts, and it's not clear (to me) if the transistor is making
a good connection.
Also, the lead spacing on the transistor is very slightly different to the
usual T05, meaning a replacement has to be 'jiggled' into it's socket.
