I am upgrading a Sansui TU-9900 tuner. The rectifier curcuit is currently four out of date diodes (1S1850). The specs are:VRRM 200
I(RM) max 10U @ 200
I(FSM) 50 @ 10m
V(FM) max 900m
I(FM) 750m @25C
I(O) max 1.5 @60CI want to upgrade to the best quality possible for sound. I'm also upgrading with quality Caps BTW.
What would I use? What parameters do I need to match or exceed? What are the key parameters you look at in replacing a diode? Do I use Shottky or Hexfred or ??
I know some of this is basic but I'd appreciate a little education.
Thanks, Denny
