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,
