Don't worry, I've built several tube-amps without succeeding in killing my wife....
Seriously, I've got a transformer that is labeled 'single phase trafo' and was wondering if it's usable as power transformer for an amp, given my false presumption that 'normal' trafo's are dual phase (to suit the mains grid which I thought was also dual phase). The guy at the electronics store told me yesterday that mains grid IS single phase, so my transformer is just your-average transformer.
However, you say the mains grid is three phase
Practically; can I use my single phase trafo on the mains grid or can it only be used in specific industrial environments where mains grid is single phase?

In the US household service is often referred to as split phase. 3 wires into the house. 2 hot 120 Volt wires and a Neutral wire. A total of 240 Volts from one hot wire to the other. Commercial and Industrial users have three phase service. 3 hot wires (and maybe or maybe not a neutral) the phase between each hot wire is 120 degrees.
So maybe the transformer in question has a 2 wire primary rather than a 3 wire center tapped primary.

A three phase transformer will have 3 cores each with it's own primary and secondary windings.

So a 3 phase transformer would look very different to a conventional single phase transformer. The fact it has 2 primary windings is usually an indication it can be setup for 120 or 240 Volt operation.
