No, the operational LTspice files have not been updated for a long time, in fact they were already outdated at the time of the first issue: they had served their purpose, and all subsequent tweakings were made on the actual instrument

Hi Elvee,
Demian remembered this thread for me. I have three complete 428B units that I'm running. I love them too. But your project would allow me to keep a modern version on the bench instead of shelves in the back. I had bought the last one as spare parts, but then noticed someone selling probes. I bought one to complete that unit.

I don't know when I'll have time to design a PCB for this project, but ultimately I'd very much like to have a pair of these meters in one box so I can monitor two currents at once.

Thanks so much for documenting your project and giving me a place to start. Your work is inspired, and many share your love for this instrument.

-Chris

Thanks for your interest.
You could ask Sam Reaves how far he is in his PCB project: he must be well advanced now.

Not to revive an old thread, but has anyone had any luck with this project?
