Thanks, Michael. You make a very good point. I ran the tests off a variable transformer at 60Hz, no load, no scope. I will redo the testing as you recommended. I need to find a generator that can supply a voltage high enough to get one volt on the secondary taps.

Now I have some work cut out for me!!!

Thanks again.

This thread is of interest to me as I have a 1000a that needs to be overhauled before it is put in service. I found the service manual on AK, the parts list section of the manual specs the OPTs as 6 kOhm primary and 8,16 Ohms secondary. No part# is mentioned.
