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. https://www.instructables.com/Tube-Curve-Tracer/ Then some added functionality came a bit later: https://www.instructables.com/Tube-Curve-Tracer-Ver-11/ 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. |

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. https://www.eevblog.com/forum/testgear/rigol-dp832-power-supply-as-automated-curve-tracer/ Does Python qualifies as a curve tracer? ;D |
