Pioneer LX 636, SR3AM-4 diode & 103z ceramic cap replacement

Hello, everyone.

I'm attempting the restoration of a Pioneer LX 626 receiver that kept blowing up fuses.

Troubleshooting the power supply assembly so far determines that two SR3AM-4 diodes are shorted and a ceramic capacitor (,01uF, 1.4kV, 103z model) is cracked open.

I'm having a hard time finding replacements for these components. Can someone help?

Thanks in advance.

Those rectifiers are 200 volt 3 amp. I would just use 1N5408, which are 1000 volt 3 amp. They can be found on eBay; same with the ceramic capacitor--anything rated at 1400 to 2kv will be OK.
