Well, I think he changed the PSUs. The single 700 I have is an older one and I can get 15.xv out of it. The two I have ganged max out at 14.2v. But, I had an issue with these when I first put them into use. He told me they were all set, just parallel them and they will do the rest. This was not the case. I put a clamp-on meter on each lead while transmitting and one PSU was delivering 40+ Amps while the other was doling out about 22 or so. So, instead of using caps and diodes, I just used two short HD jumpers to parallel the two, then connected my positive load on one PSU and the negative on the other. They pull evenly now and work flawlessly on 14.2v. When the amp is drawing about 62 Amps, the voltage drops to about 13.9vGregT -
Do you run your two S700- 12s at 14.2 vdc in parallel ?? Mega Watt recommends 13.9 max when running in parallel. Does operating at 14.2vdc seem to work OK ?? If so, I will boost my voltage a bit
