Does anyone know the acceptable tolerance for the high voltage secondary portion of the PA060 type power transformer in no-load condition?
I see specs show 360 55 0 360 but mine is measuring 345 65 0 355 with the specified primary voltage.
How critical are these voltages in the ST-70 and if so what should I watch out for?
All the low voltages are spot on.
Any suggestion/schematic for a load condition test that would somewhat replicate loads in the ST-70?
