Testing a Yoke: Eico 944

[Montman]

Testing my first yoke coil : Stancor DY-1 . My EICO 944 yoke tester instructions says in order to test it correctly, the shunt resistors across the coils have to be removed first. I haven't pulled the yoke yet, but are they the resistors in the yoke that have to be removed? Has anyone ever done this before? It tested bad when I did the vertical coils which have the shunt resistors across the coils.

Any advise would be appreciated.

Also, if it tests bad, anyone know where I can get a tested Stancor DY-1 for an Emerson 571?
