--Hi, all. Does anyone know how to get a fan kit for the TS Sweet Sixteen to work? I installed it, easy enough, plugged in the 1/4 inch plugs, but nothing happened. Is the kit supposed to blow air as soon as it is hooked up, or does the kit only work when the amp/heat sinks get a certain temperature? Thanks for your help. |

--Well, I opened up the amplifier and checked for voltage at the "Fan" connector. No voltage at all. So, something is either messed up, or a thermistor or whatever controls the fan output. Ugh, what is the dealio? Thanks. |

--Well, I found a schematic online and it seems to show one end of the wire (I mean the wire connected to the 1/4 inch fan output on the back of the amplifier) going to chassis ground and the other end goes to an "S3" and right underneath, it reads "115°F", so that makes me think it is activated by a specific temperature. I guess we will see if the fans come on now. |

--Haha, I found out if I do a little investigating, I can figure it out for myself. It turns out that the fans do indeed come on at a specific temperature. Whether or not it is 115°F, I dunno. I would like for the fans to come on a bit sooner (like at maybe 100°F give or take), but this fan kit that Texas Star puts together certainly does the job! I'm glad I got it. It even cools the bottom of the amp. Catch you on the airwaves! |

I think that those amps have a sensor to tell the fans when to come on. Call galaxy radio repair they make texas star amps. They will tell you everything you need to know |

Mayor513, I would'nt worry about the fan coming on sooner. Amps get way hotter than 115 degress and work fine. Just think, our bodies are only 98.6 degress. 100 degress would'nt really even be warm to the touch I don't think.
Hope to catch in DX land soon!

--Yeah, I was just a little anxious trying to get that fan kit to work. I figured the fan kit would immediately start working as soon as I plugged it in. When it didn't, I was like "What the heck?"
--I am happy with my fan kit, it works great and like it should, but what I would like to see packaged with the fan kit is a short note explaining that the fan kit does NOT start up immediately and that the amplifier has to reach a certain temperature before it starts blowing air into/onto the amplifier. Maybe most people know how the fan kit is supposed to work (about how it only comes on when the amp. is a certain temp., I mean), but for folks like me that wondered why the fans didn't come on at first (and there are many of us, I'm sure, haha) a helpful note would help. |

Hey man how do you like that sweet 16. What size alternator do you have to run that. im thinking of getting one, but just am not sure. Remember if you run a low dead key it's gonna take a long time for those fans to come on. That amp is pretty bullet proof from what i've heard. You can really drop the hammer with that thing. |

--Audiophile73, I really like the amp. I don't run it mobile, just base. Keep the SWR low and keep the amplifier DK fairly low and it will last a lifetime. I will probably keep it around 150 DK give or take. It never gets too hot. It should scream on SSB too. |

when i got my 1st dx1600, i wasn't happy with waiting for the fans to kick on, either. SO, i removed the little thermistor thingie so the fans would run constantly. it took about a year, but all 4 burned out within a week of each other. i replaced 'em with 4 bigger fans that i screwed to little plastic molys pushed into the cooling fins (like you put in sheetrock to hold up pictures). i generated quite a bit of heat due to overdriving the texas star. it took it though! sitting on a shelf, but it still works! |

--Hi, Draft. Right now, all I have is the 70 amp Astron power supply, however, I am not trying to run the amp at full output with only 70 amps, haha. Though I plan on getting a larger power supply in the future, I am only running anywhere from 50 watts to 200 watts out of the Texas Star, so both the amplifier and power supply are being run well under their max. ratings.
--Patzerozero, is that thermistor (or whatever it is called) the black thingie that has a wire coming out of both ends (axial) ? I don't have the amplifier opened up right now, but that component sounds familiar. What I might do, is to not remove it entirely, but place it on a switch, that way I can either let it work as normal, or press the switch and let the fans start working before there is any heat buildup. Catch ya later. |

that's it mayor. i think it would be just easier to remove the thermistor altogether & let then fans run. back when i ran my 1600, it was 5 days a week, 10+ hours a day & weekends for pleasure. my fans burned out, but more 'normal' useage & they'd probably last a long time. if somebody did NOT yet have the fan kit, i would recommend my above suggestion, rather then spending money on the kit. |
