I used to head along every year then got a little lazy, I finally got back into the saddle in 2019 – only for covid to cancel the 2020 and 2021 events. 🙁

The DC power supply was predominately used to run lifts in nearby buildings – the last consumer finally migrated in 2003.

Those mercury arc rectifiers are a wonderfully mysterious piece of equipment – very 1920s/30s sci-fi.

What functions in the Melbourne CBD require DC power?

We came so close to being able to bring a live program for Open House in 2021. Stay tuned for Open House Bendigo later this year and a live program for Open House Melbourne in 2022.
