If you need to make a cable, make a pin for pin cable and you will be good to go.
It should follow the standard Asian pinout found in Asian made tube mics.
You could work out the pin out if you have the psu and a dmm.

I do have the power supply and a DMM, how would I go about this? Thanks!

well what are you wanting to achieve here.
Do you have the supply and are repurposing it for something else or what?
If it were me I would take the lid off.
From there you can visually see which pins are ground,which pins contain audio.
The audio pins will go from the 7 pin to the 3 pin xlr.
That takes care of 3 pins right there
This leaves you with pattern, b+, heater and additional ground connections.
you can see which pins are ground pins. You can measure continuity for ground to chassis.
Then you can measure vdc in reference to ground and see which pins are which.
I also found this schematic for a groove tubes
The st-69 is basically a groove tubes gt-67 I am told. So check these out.
Measure with a dmm and confirm the pins out to be safe.
