I have ordered the parts to build your single 9V dc beck's blood cleaner, and now await their arrival.
Can you tell me if yours is a Bi-Phasic design as Bob Beck states it should be to perform well? I mean by Bi-Phasic, to be able to switch between a positive voltage and a negative voltage. Like between +33v and -33v, and not simply between +33v and 0v.
You have done a wonderful job of putting all this info together, so much so that I feel confident to build it myself.
