Question about diodes

[drbacklash]

I'm new in this Sansui restoration thing and I'm making some progress by reading the AK Sansui forum. I've replaced many caps, resistors and transistors on my G-6000 but I've hit a wall with the diodes. Can I use the Sansui numbers to cross-reference to substitutes? For example, what does a 1S2473D relate to today? I can't seem to find a cross-reference for that number (or any number, for that matter) anywhere.

The Zeners are even worse. Can't find a EQA01-13R anywhere. What is the best way to identify current diodes and where do I get them?

Thanks for helping a newbie.

Hi,

Diode EQA01-13 is a Zener diode, 13V, 1/2W. 5% tol.
Equivalent to NTE-5022A see below:

While Diode 1S2473D is a germanium diode general purpose equivalent to
1S188AM from site below you can see more NTE equivalent

This might be some more general help for a bigger picture understanding:
