Could be, but at least a microwave oven transformer is capable of supplying some
power - this thing was supplying virtually nothing. Had even the primary current
been 3.15A @ 240 V, it would imply a power of over 700 W, which at 2.6 kV would
have been a few hundred mA.
The size at least would suggest it was quite a power transformer - it was not
easy for one person to lift.
