Re: A Vacuum Tube Curve Tracer for all Tek Semiconductor Curve Trace
Hi Bruce,
I will take a look at Vector. I was aware they sold them in the past but I
am not sure about now.

Vector used to sell little extruded round aluminum cans with 7-pin and 9-pin tube pin bases. The bases attached with side screws. These were used for constructing special plug-in modules. I don't

Hi David,
Sorry for the confusion. I'm looking for plugs, not sockets. There are lots
of sockets available in many different configurations. So far there are only
two socket saver variations (9-pin

Hi Butch,
Thanks for your first post. I hope you find reasons to do more in the
future.

Re: A Vacuum Tube Curve Tracer for all Tek Semiconductor Curve Trace
Hi Ed,
That is actually possible to do. The first plug I made was done in a similar
way. Your way would result in two at a time. But that still takes a
considerable amount of time to do. The 8-pin and

Re: A Vacuum Tube Curve Tracer for all Tek Semiconductor Curve Trace
Hi Dave,
I need one or two.
I did find a source for 9-pin socket savers. Those can be opened up and the
plug part separated from the socket. They are less than $3 so I will buy
those. Same for 8-pin

Re: A Vacuum Tube Curve Tracer for all Tek Semiconductor Curve Trace
At this point I am not sure if you are looking for a socket or a plug
but in either case, they make pins and large collet sockets which can
be swaged or soldered into printed circuit board material.

Re: CORRECTED POST : Tek 2445 vs Tek 2430A (Tek 2435A)
In 1991, the 2445B was $4000 and the 2430A was $8000 from Tektronix
but it would not surprise me of Tektronix sold more entry level 2430/A
DSOs than low bandwidth 2445/A/B analog oscilloscopes leading

How many of the 7 and 9 pin plugs do you need? Are you looking for a
significant number?
