Hi Shaan,
The PSU board is rated from +/-20V to +/-56V.
I have a 500VA toroidal transformer with secondarys @ 40VAC, giving a rectified rail voltage a smidge over 56VDC.
May I ask what particular components are critical for the rail voltage to go to +/-58VDC?
kind regards
stevet

Hi Shaan,
Looking at the circuit, the rectification part should not be a problem with slightly higher voltages. I see you have sized things up for a maximum of 10amps, and my transformer is 6amps-ish . I guess the area to look at for slightly higher voltage is the sensing side of the circuitry.
kind regards
stevet

Hi Stevet.

Other than a higher calculated value of R9,10,11,12 and 2Watt rating for them there is nothing that needs to be changed for 58V. I have tested it with maximum 56V so mentioned only that in first post.
