It seemed like such a good idea at the time.
I’ve wanted an autotransformer for electronic troubleshooting work for a while. Autotransformers are variable transformers that let you bring the AC voltage up slowly on a piece of gear under test. I owned a Radio Shack/Micronta variable transformer for decades, but it didn’t survive my move to … Read More → "Pimping My Variac Autotransformer (Actually, it’s a Philmore)"
