Ron,
I have an SC-61 setting in the corner with the case off.
I pulled the high voltage power supply board an checked the fly.
In Circuit;
Dick smith LOPT/FBT tester: no LEDs lit.
Sencore LC 75: 0 rings
Sencore VA-48: 0 rings
Out of Circuit;
Dick smith; three LEDs lit
LC-75: 22 rings
VA-48: 5 rings
So the Dick Smith and the VA-48 shows it to be bad even though this is a
working transformer.
