Re: 'Soft' transistor sockets
The thinking was:toggle quoted messageShow quoted text
... transistors are expensive, very variable in their gain
from one example to the next, and we are not so convinced
that they are any more reliable than vacuum tubes. So, we
need sockets for the transistors, ... a lot of sockets...
but the available sockets are so expensive, and take up a
lot of room, and are not all that reliable...
The little insert pin sockets that tektronix used are very,
very reliable, and the silicone gasket at their entrance can
take the heat of soldering, and keeps foreign materials out
of the socket... Plus, it adds a little more resistance to
the transistor falling out of the socket.
Tektronix found over time that transistors got cheaper, and
were much more reliable than any sockets you could use to
mount them, so they went to directly soldering the transistors
into the circuit board.
