[Amps] Transformer i.d.

[TexasRF at aol.com]

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?
