3 X 50 Amp supply setup should be fine after volages are matched. some of you have been a huge help with info on this for me and I appreciate it. I know this is more of a pain to setup and an straight AC setup is more practical or easier to do but as I said Im not gonna let this 1600 sit anymore its a waste of $$ to do so. Now what gauge wire would you reccomend for connections I know theres 8 guage comming out of the amplifier but should I then go into 6 or 4 gauge at this point and inbetween power supplies? I also think I will hunt for another legal limit antenna tuner for this setup. What has actually been seen come out of one of these 1600 for output power AM/FM SSB/CW?? Im going to start this within the next 2 weeks I think if its not ssold by then this is what I am working with and have any of you seen a fankit like this?? Its different than the Texas Star fankit Texas Star sells 2 different covers 1 top 1 bottom each with 2 fans if you look mine has just the clear plastic top cover with 4 high flow fans and I cant believe how these Comair Rotron fans push air I blow air halfway across the room from out of the ends of this cover it certainly will keep a guy from worrying about overheating. The only thing is I see where the remote head 3/4 inch plug goes into the amplier theres a 3/4 inch plugin slot for the fan kit my fankit has a couled cigarette adapter wired to it and I see that the amp has a fan thermostat that controls when the fans come on and turn off. I believe that itb was on at 115 degrees and shut off at 105 degrees so instead of fans running constantly pulling in dust and and eventually wearing out Im going to put a 3/4 in plug on instead of the cigarette lighter adaptor and utilize the automatic thermostat unless the thermostat is not part of the internals of the amp ad was exclusively on Texas Stars fankit anyone know anything about this?
