Sorry to say Enzo is recuperating.
There are not any schematics to be had for this model.

Try to figure out what type of diodes they were. Is the part number readable? Are there other good diodes on the board with similar packages?

They are probably the secondary rectifiers, and they most likely failed because the power amps blew and shorted the power supply. So, check the power amps for shorted output transistors.

Than you Mr.
Diodes D30 & D31,was in parallel whit two electrilitic (C2 & C3), 2200 uf x 200v, in opposite polarity.
I suppose are to do short whit inverse peak.
But there are not other similar in board.
