transformer readings-out of the amp

[poundy]

i have 3 identical transformers that im trying to establish if they are ok or not


all readings are between each of the outputs and the ground wire for each tapping


these all came from NAD 3130 amps

and all the transformers are out of the casings.



Transformer no 1


TA 1 cable 1-10.7 ohms
cable 2-10.8 ohms




TA 4 8ohms switch position
cable 1- 1 ohm
cable 2- 4.5 ohms


4 ohms switch position
cable 1- 1.5 ohms
cable 2- 2.1 ohms


Transformer no 2


TA 1 cable 1- 10.7 ohms
cable 2- 10.3 ohms




TA 4 8ohms switch position
cable 1- 0.5 ohms
cable 2- 0.4 ohms


4 ohms switch position
cable 1- 0.6 ohms
cable 2- 0.6ohms




Transformer no 3



TA 1 cable 1- 10.4 ohms
cable 2- 10.3 ohms




TA 4 8ohms switch position
cable 1- 0.8 ohm
cable 2- 1.2 ohms


4 ohms switch position
cable 1- 1.1 ohms
cable 2- 1.3 ohms


i can see consistancy with the TA 1 pairs so they are ok i guess, but the others im not sure about.


cheers, paul
