I recently picked up a medical grade 3KVA toroidal isolation
transformer. It has dual primaries and secondaries so in addition to
being a isolation transformer it can be used as a step up/down
transformer. I had two ideas in mind. One was to use it as a 1:1
isolation transformer when working on radios with a hot chassis. The
other was to use it as a 2:1 step down transformer for a linear map I
have with a 120V primary transformer. This thing draws too much current
to use on 120V unless you have a special dedicated line. With this
transformer I could step down a 240V line to 120V. Since this is an
isolation transformer, I am assuming I would need to have a direct
ground connection for the amp. I am I correct or is something else needed?
