Hello!! I just acquired a General Electric UPX-003B phono pre-amp (to be used with a GE VR II & a GE RPX pick up). I plan on doing a complete overhaul, which would include replacing the (half wave) selenium rectifier. I have read that some people suggest changing the half wave rectifier over to a full wave rectifier, but I am not 100% sure on how to do this.....I usually avoid sets with selenium rectifiers, just because I don't like dealing with them, call it seleniphobia… I did replace a selenium bridge with a silicon bridge on my Philips AG9016. But that was just about a "drop in" as it gets. The only difference was adding a voltage dropping resistor between the rectifier and first filter cap. So here is my question (which I hope makes sense). The current rectifier in the UPX-003B has the lead from the power transformer connected to the (+) section, and then the (-) section is connected to one of the sections of the filter can cap......And that's it.... A rectifier bridge (I would buy a rectifier bridge because of space constraints) has 4 lugs: 2 = AC 1= (+) 1 = (-)…….. Would I...…..Attach the lead from the transformer to 1 of the AC lugs of the rectifier, then the (+) to the filter cap and the (-) to the chassis (and just let the other AC lug unused)??? Thanks for reading!!! RC.
