Sure, they're used a fair amount for low-Z resistive stuff. I have a bunch of old mu-metal shielded transformers for ribbon mic preamps that I've never actually used for anything. ;) Win and Paul made a pretty cool low-noise front en

Er... if it's a power supply being probed, how do you transformer-enhance without putting a short on the power supply? For low impedance at high ground-relative voltages, the current-sense instrument amps like INA283 more-or-less fill

Not necessarily when it has a thin metal coating to reflect infra-red radiation. Such glass is mandatory for all new windows here. John

[about a bug zapper] The 'transformer' may be a potted circuit, with current limits like in a neon transformer. It won't be tightly line-coupled like an ideal power transformer. The human threshold has to do with heart-stoppage; th
