Default U67 power supply help needed

I'm trying to repair a NU67 power supply. Someone had
cobbled together what looks to be a bridge rectifier by
soldering 4 diodes together to replace Gr2. It looks to
be a very half-assed job.

The schematic reads B30 C500/250

My electronic knowledge is somewhat limited. What are
the values of this component? What type of package?

Thanks.

The original number is a European bridge rectifier number,
that translates to 2A and 100 PIV. Almost any modern devices
would be a perfectly fine replacement.

If the separate diodes bug you, you could replace them
with any modern bridge rectifier package of bigger ratings.
Pick one at maybe 4 amps and 1000 PIV. About a buck and a
half or so. But the separate diodes will work fine is
the soldering and such looks good.

Good fortune,
