diode CT-2A05

Hello All! How to replace subjects? The bridge on them is made in a regular Chinese AT BP... A couple of them are broken... I haven’t found any analogues; I haven’t yet been able to disassemble other power supplies and select analogues based on them. I want... By the way, I have a dead Soviet AT BP 200W, so there are 3 separate ones at the input bridge. The diodes are in the form of 6*9mm cylinders, brown (some black) with yellow stripe. What is this? Will it fit? It confuses me that the Soviet power supply has 3 separate circuits - maybe they have a current of 2-3 times less than the subject... PS By the way, what could have led to this breakdown? Otherwise I’ll change it - and they’ll immediately they'll fly again... Best regards, Evgeniy.
