[Central-Electronics] 20A diode bridge

[Mike Wells]

Thank you for all the helpful responses, I certainly appreciate your feedback and information on possible options. I also appreciate the friendly comments on this subject. Alan has a few extra geranium diodes that he has offered up, so I will send a direct email to him with my information.
Thanks again for your replies.
