SX 780 diode replacement

Bernardz

Member
I’m in the process of replacing my diodes on my Pioneer SX780 only because of the age of the unit and also replacing the filter capacitors .

The original diodes are
SR3AM-8 4-each
S1B01-02 4-each

A supplier told me that a suitable replacement for the
SR3AM-8 Replacement 1N5404
S1B01-02 Replacement 1N4004

The replacement diodes seem much small in physical size than the originals. I know modern technology has improved many of our electronic components to have equal or higher values in small physical sizes.
This is my first venture replacing my diodes and I would appreciate any guidance or advise . I really don’t know too much in this area and I know this forum has very knowledgeable people who can guide me through this issue
I’ve attached both cit sheets for the diodes , forgive my lack of understanding , but I don’t know how to interpret the values
Bernard.
