Servo-balanced outputs provide automatic output level adjustment to accommodate either balanced or unbalanced feeds. If you have an RTA you can use that to determine where you are. During start up the initial surge current will be higher with the much larger capacitors, k552 could potentially over load and fry the original rectifier diodes.
