Default High voltage capacitor and diode replacement for Koss ESP-9

I have lost one of the 2 circuit board of the transformer of the Koss ESP-9 so i'm building a new board to replace the lost one but i'm having hard time finding appropriate parts.
1. C1-C12 There are a lot of high voltage capacitor avaiable at mouser, x5r or x7r is fine?
2. D7-D14: I can't find a 175V zener at mouser, is 170V or 180V ok? and does the power rating need to be high?
3. D1-D6: can someone suggest some type of rectifier diode that can replace the original MV16A?
Thanks a lot!
