I have a 4d4b42 diode rectifier that needs replacing, I'm having trouble cross referencing part #. It's on a power supply board out of a Yamaha clavinova electronic piano. It's from 1985.i found demon also used this br in their audio amps, but has been discontinued and I can't seem to locate any data info, really any info about part replacement. Any help would be appreciated.thanks in advance
