Tweakers' Asylum Tweaks for systems, rooms and Do It Yourself (DIY) help. FAQ. |

I have a couple of Yamaha B-2’s that I use for bi-amping. Mods so far are recapping all electrolytics, new gold RCA jacks wired directly to the driver board (bypassing all front volume controls and switches), power supply caps bypassed w/polycarbonates, hardwired audiophile power cord, replaced speaker protection relays and installed new gold 5-way speaker binding posts. The power supply section uses Toshiba dual diodes S5151 & S5151R as a rectifier bridge. From what I can gather (can’t actually find a spec sheet), these are 200volt 5amp devices. Does anyone know if that is correct of sounds reasonable? It doesn’t appear that the fact they are ‘dual diodes’ means anything except maybe convenience of packaging and assembly. I’m planning to replace them with FRED’s spec’d to handle that voltage and amperage, is that OK? I want to be sure as I can't afford to toast the unobtainable VFET's.
