The MUR860 diodes have a maximum current output of 8A.

The maximum current output from a LM3886 is 11.5A.

Are these diodes in a rectifier bridge still suitable if you are planning to get close to maximum power out of a LM3886?

May be that is the reason why peranders used MUR3020 also in parallel to MUR820 in his design in the Industrial SMD gain clone project.

I suspect that 8A diodes will work pretty good. You don't take out 11.5 A continuously (the LM3886 won't handle it) and secondly, the music isn't DC current. Notice also that the diodes will share the current because you have four of them.

I have an option for TO247/TO220 diodes in my QRP02 amp just for flexibility. I my case I have also fuses which breaks long for before 11.5A
