Can you reference your new AC technique?

I was pointed to a site called:-

http://www.silver-colloids.com/

Which has some of the most useful and bluntest raw technical data I've seen associated with colloidal silver. It indicated that most simple DC silver preparation tends to produce ionic silver as opposed to the proper useful silver suspension associated with a colloidal liquid.

A quick skim over the 'net showed simple AC units using just a transformer connected to the electrodes with no current limiting, while other more sophisticated units described using AC but with fluid conduction monitoring to shut off the current when the desired conductivity was reached.

I wonder if there is an optimum frequency for the fastest and most stable preparation of good colloidal silver with a high ratio of actual metal in suspension as opposed to the electron stripped ionic silver.
Yes, I published the equation for it years ago on this list. I don't remember the equation any more, but for 2 minute cycle time it comes out to about 20 volts, for 50 hertz about 9 KV and for 60 hertz about 10 KV.

Would perhaps 1Hz or even 0.01Hz be better? 50/60Hz would be ideal, since it comes that way out the box so to speak.

That question makes no sense.  The proper frequency depends on the voltage.
