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

Yes, and i'm actually going to replace 7 low amperage fuses with solid copper rods.  The two main higher amperage fuses i will replace with aliexpress Aucharm fuses...with a rating of 1amp higher than what was taken out...just to get the size of the wire a bit larger.

@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.
