Well, as it turns out, finding type T alloy female crimp connectors around
here turns out to be more difficult than I thought it would be. Therefore,
what part number and supplier should I tell those handling the purchasing
to get for these type T alloy female crimp connectors, and what part number
and supplier should I use for a nonmagnetic DB 9 connector to go to the probe?
Thank-you,

Hi Bruce,
In the files section<
https://ammrl.groups.io/g/main/files> of ammrl.group.io, there are
a number of hardware manuals. The pinout you are looking for is on page 10 of the
Highland VT controller manual. Note that two of the pins need to be type T alloys,
not the standard copper of replacement DB 9 connectors.

>From the manual:
4.2.1 Probe Connector J101 (Rev C Units)
The rear-panel 9-pin probe connector J101 is a female, 9-pin D-SUB type. The two thermocouple-input pins
are of type 'T' alloys, and the mating connector must have corresponding thermocouple alloy crimp pins.
Pinout is as follows:
1. Thermocouple + Copper wire/pin alloy
2. Ground
3. Thermocouple -Constantin wire/pin alloy
4. n/c
5. n/c
6. Heater highside drive
7. Heater lowside drive (ground return)
8. Safety R TD low side
9. Safety R TD high side
