[Amps] Henry Transformer

[Carl]

Most 8K's run on 240V single phase, some commercial versions use 3 phase.

As in our private communications, the ECA-1028 was used in the Henry 2000D 
amplifier. I don't know about the 4K Ultra. The manual refers to a Henry 
part number, B4-75448, but does not reference an "EC" number like most of 
the other Henry amplifier manuals. The 8K-Ultra uses an EC-26142 which is a 
3-phase transformer.

I have the same transformer (ECA 1028) and I am trying to find out its 
specs.

Did anyone come up with the info on it? I think it came out of a 4k
Ultra, but possibly an 8K Ultra!

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?
