    Question Replacement of components in a PSU

    Well, I'll even go tomorrow to buy new components for my power supply. I am going to replace the 12V line capacitors that are currently two YHC from 1500uF to 16V each for two TEAPOs from 2200uF to 16V. I'll put a filter coil in the transient filtering stage. I will replace the GBU4J rectifier bridge with a GBU806 or GBU 606 (I will buy sinks).
    But I want tips on the 12V rectifier that is currently an MBR20150CT. I was thinking of replacing it with an MBR30150CT or SBR30A60CT. Do you have any recommendations in mind in case of the unavailability of these two models? Preferably one of 40 Amp Shottky.
    One more thing. The MBR20150CT has this specification of 150V on Vrrm. It can be replaced with a 60V without problems?
    Thank you guys.

    Upping the capacitance can be a bad idea, as it can reduce the conduction angle, which increases the RMS current and so heating. It will also increase the start-up surge.
