Show Us Your Curve Tracer

Yes sure I'll help.
I use two transformers. One is 2x15V 0,5A for the OP's and CMOS stuff and a big toroid that used to give 2x44V output and I've added a few windings to get it up to 2x60V.
Ah yes, those Siemens Relais are long obsolete but not really necessary. Just use regular Relais, there's nothing special about them.

Digital, smidgital...I've probably posted about this before but here is my home-built tube curve tracer. I used it to answer a question about the biasing of some 6AU6's in a stereo amp I was making.
This is the first attempt at making it, which proved successful enough.

Then some added functionality came a bit later:

A word about my build style. I don't like to spend a lot of money. So parts are usually drawn from my glory boxes and whatever I have on hand. If I can find enough workable stuff then it may happen that I spend exactly $0 on a project. And so it was with this one.
Included is a shot of it in use and a shot of the HP 1741A showing the curves for one triode in a 12AX7 tube.

Thanks! 😎

This is from a Python script sending SCPI commands to a Rigol DP832 power supply, in order to browse/measure Vgs, Vds and Ids of a PHP45N03LT TrenchMOS.

Does Python qualifies as a curve tracer? ;D
