Will skinny-leg diode restrict amperage compared to fat-leg bridge rectifier?


Hi All,

I want to do some modifications to my power amplifier, to see if i can hear an improvement in sound...but have come across a potential issue.

I want to replace the main bridge rectifier with zero recovery time SiC diodes.

I have a fear that if i replace the fat-legged bridge rectifier (Image 1 below), with a Cree SiC diode assembly, like in Image 2 below, that the skinny legs of the Cree diodes will restrict amperage, even though the Cree diodes are rated at the same amperage as the fat-legged bridge rectifier.  

What's your peoples take on this?

Image 1 - fat legged bridge rectifier

Image 2 - skinny legged Cree diode assembly

@imhififan there is no fuse that blow at start-up.  I am just exploring amplifier performance enhancements, at the expense of amplifier safety, by bypassing the 7 low amperage internal fuses.  Personal safety (e.g. house burning down) is not compromised because i am keeping the 2 external fuses in place.

Since the mains fuse can pass inrush current which is much higher than the rated value, why worry it will restrict current flow?

Experiment is a procedure to support or refute a hypothesis! 👍

BTW, what amplifier it is?
