Yes, those diodes will replace those bulky selenium rectifiers, but be careful of diode polarity. Some selenium rectifiers have a + mark which actually goes to the electrolytic capacitors, which is the cathode side of the diode marked with the strip on the diodes. Bring it up slowly, measuring the voltages at the electrolytic filter capacitors making sure the polarity is right. If you have a variac, even just apply 10 volts or less to start and check the voltages on the capacitors. You don't need to blow the electrolytic capacitors or the power transformer. Very nice wiring job.
