Wondering how the o/c electro could have caused the voltage to sag. Also
thinking that the 330 ohm resistor runs a bit hot - one can see that the
board is heat stressed around this component. It would be passing 40 ma.


It was probaby there to stabilise the current sense, and without it the
current limiter was kicking in when a load was connected due to the sudden
output voltage dip.

Just a guess mind, it's hard to say without seeing it.
