While I was not engaged in ham radio for the last almost 30 years, I was being a kind of a audiophile for some time. The figure shows one of the devices I obtained during that period, the model NSIT-2000PLUS Mark II.

It is an isolation transformer, mainly used for your audio power amplifiers, and coverts 200V AC input to 100/115V AC output, with optional separate smaller transformers for your less power consuming equipment, such as an A/D and/or D/A converters;

Do you think this device is also effective for your rigs which deal with RF signals?
