Glen,you can tell a lot about the transformer by connecting 12vac to the
primary and making some voltage checks on the secondary terminals. That will
at least identify the turns ratio and presence of center taps etc with a
relatively low voltage.
Once the major winding and tap windings of the secondary are identified
you can connect 120vac to the secondary and do some sleuthing of the primary
terminals for more info.

I now have a transformer that is reportedly rated at 3000 volts at 1 amp.
The transformer is supposedly from either a Henry or Alpha amplifier. It
weighs about 70 pounds. The nomenclature is as follows:
Elect Corp of America
South Gate
p/n ECA 1028
Unfortunately, there is no other information on the transformer such as
which terminal is which tap on the secondary. The primary terminals are
obvious, they are completely different from the terminals on the secondary.
The primary terminals are numbered 6, 7, and 8. These are very large solder
terminals.
The secondary terminals are numbered 1, 2, 3, 4, and 5. These are machine
screw studs mounted on an insulating material. What I really need to
know is how these 5 terminals are configured. I sincerely don't want to have
to apply voltage and then measure the voltage.
Anyone have some information on this particular transformer?
