1N4007 good replacement for a V30n?

I have a V30n diode in the pulse power supply of a Sony TA-F60. From what I can find it’s a 600v 1.0A schottky. Will a 1N4007 work in its place?

What about an MV203V? Can’t really find much on it, but it looks like one of the V1212 style diodes that are suggested to be removed.

This makes the V30N look like a .4a 1500v diode:

Thank you, of course I made the mistake of looking at NTE for the info. They have it at 600v 1 amp, but it definitely looks to be 1500v.

Would this solid state integrated power supply see anywhere near that voltage? I would think a 1000v would be more than sufficient.

NTE site shows NTE552 as their sub. For that part number. Maybe a 1N4937 instead.

Thank you for the suggestion, but that looks to be a 600v diode which NTE has wrong.

Any suggestions for the MV203V diode? All I can find on it it that it’s a Sony specific diode I guess.

The caps in the picture are rated at 16Volt and if that transistor is a 2SC1583 it’s 50volt.

This thing is D905 in the schematic and it is in circuit to a cap rated at 47uf / 50volt. Don’t see the worry for such high voltage rating.
