    Quad cap voltage rating on later stages Empty Quad cap voltage rating on later stages

    I'm looking to replace the quad cap in my Stereo 70 with modern radial electrolytics.

    The stereo 70 manual shows expected voltages of 435V / 415V / 375V / 305V.  From what I understand, surge voltage will be quite a bit higher and 120V line voltage will also increase these expected voltages.

    I've sourced some 500V Nichicon caps and will use 2x caps in series for the first stage and second stage (with resistors to balance voltage).

    The third and fourth stage would seem ok with a 500V rated cap.

    Or, do I need to be more conservative here with surge voltage + 120V line voltage?
