I have one. It's okay, but if you have not already bought it, DON'T. It's not worth the money. I also have a COPPER KL-500. There is no comparison between the two amps. The only thing really good I could say about the Galaxy 350 is they made the fuses real easy to change. Plus they are automotive blade type and easy to purchase... It is 4 stage and does work nicely with less than 3 Watts input AM. It runs VERY hot. I added a 12V fan to the bottom to keep it cool and never run it past stage 2 or 3. It puts out about 175 Watts to 225 Watts max for me, but as I said, I keep it around 125 Watts out.
Hope this helps you.

Thanks Ca346. I've had it for quite awhile but never used it. It sounded good athe time plus it had a pre-amp. |

Well then.... I highly recommend the above because it really gets hot. Drill a 1 inch hole in the bottom flat plastic over the fuse if it doesn't have one yet. Otherwise, the first time you blow one, you will have to take the amp apart to get to the fuse. With the access hole, a pair of needle nose pliars with pull the fuse and replace it. It also serves as an exhuast hole for step number two. Next go to "www.allectronics.com" and buy a 12V fan to install in the bottom also. Less than $10.
The pre-amp does work well. |

If that is the "blue face" Galaxy 350, it's one of the cleanest class AB1 amplifiers available to the CB or 10m market. |

Also, if installing a fan it should be over the heat sink, not blowing in the chassis. |

those do get hot. i use a 3.5" or 4" fan. you can tie it into the on/off switch so you can turn it on/off with the amp. when mounting it, i turn it 45* away from the corners of the amp. in other words the corners of the fan are aimed at the sides of the amp. it looks like a diamond laying on top of the fins of the amp. 2 screws are all you need to mount the fan to the fins/heatsink.
oh yeah, make sure you use a brushless fan to keep noise from getting into the amp and then back into the radio. |

So, if I understand the concept, the air blowing into or accross the fins is better than blowing into the amp (circuit board) itself? Major design flaw in my approach?? BUMMER! 
Mine "seems" to be running much cooler, but sounds like I might be in denial?? (Not the River in EGYPT)
Should I move the fan over the fins on top? |

The fins or heat sink is what is designed to dissapate the heat of the transistors. Keep the sink cooler and you keep the system cooler. |

Thanks. I will rethink my cooling design. You know, on the COPPER KL-500 I also have, the cooling fins are twice as thick and twice as high as the Galaxy 350. Must be why the COPPER KL-500 never gets hot? |

I thought I would show you what the old blue face looks like...
