RE: 5R4G and 5U4G condenser output value

Posted by Tre' on January 21, 2017 at 16:54:31:
"You might also think about a thermister on the line side of the power transformer to slow warm up."

The stated limit for the input cap value has nothing to do with turn on surge.

It has everything to do with peak repetitive charging current.

This is a "surge" that happen at twice the line frequency for as long as the unit is powered up.
