Simon, it depends on your chemistry and anodes. Get documentation and follow it, i don't know what are you using but am sure my setup is way different than yours. A quick search for values using copper anodes gave 3 to 4A dm� direct 10ms and 8 to 9A reverse 0.5ms but with phosphoric copper anodes and additives, can you get these?? If not forget reverse pulses, if yes you can go with DC, and no need to waste money with reverse pulse driver. I opt for reverse pulses after find a complex to build way to avoid buying copper anodes and maybe additives, trying to spend money wiser not for having everything possible. Avoiding phosphoric copper anodes, additives and reverse pulses is what started this thread and is what people want, such method exist and i should go with it too. To avoid activation chemistries i tried to describe a possible mechanical way to go, but i don't know results. Ohh and i just realize that i misused suppressor word by the 100th time, (i confuse it with leveler all the time) and bought the additive i wasn't looking for, also i have plenty posts with this incorrect (and other things...). Please accept my apologies. Simao
