Can someone recommend an amp somewhere around 100 watts? I don't need anything larger that 100 watts in my area. It would be nice though to come up and over all the noise that is sometimes out there. Also, a link to said amp if possible.
Thanks,
Jay |

Thanks Lon. That pretty much fits the bill for what I'm looking for. How reliable are these units? Is there anywhere you know of where I can maybe get a user review on these?
Thanks for helping,
Jay |

Dexter30,
I have personally used many of the KL-200P Amplifiers before.
They are a Very Good Reliable little amp. 
I do Suggest you ONLY drive it with 2 to 2-1/2 watts of drive.
Also it has the Built in Pre-Amp so I suggest if you are driving around be Careful around other's that may be also running an amplifier so you do not over load it.
I also know of many people who use this little Amp for their base radios running it off of a power supply.

I've found the KL amps to be very reliable. I have previously had the 300 and the 500. Now I run a 5 pill "FATBOY" One thing...BUY THE SPECIAL INTERNAL FUSES from Copper that fit these amps...ONLY COPPER has these ¾" 12 watt fuses. The fuses are just a precautonary measure, in case you cross a wire or somethng, like I did! Duhhh |

Thanks for helping out guys. The wife asked me what I want for my birthday and I think I know what the answer will be now.
Later,

For the same money, I like the KL-203 better than the 200p. |

Interesting opinion Highlander. Can you tell me why this is? I'd like to have as many opinions as possible.
Patzerozero, same thing here but I was well behaved this time and didn't go crazy. Besides, my birthday is so close to Christmas that I usually end up making out pretty well.

Well, for one thing, I don't like the fact that the pre-amp on the 200p is always on. The other thing is the200p has one 1446 transistor. That's a 70 watt transistor, and they are calling it a 200? Dream on. The 203 has 3 RM-3 Mosfets in it, it will put out more power reliably than the 200p. Plus, I owned one(203), and since I sold it, it has been through several pairs of hands here in my area, and it is still kicking butt after nearly 3 years and at least 4 owners. |

I myself had some concerns about the pre-amp being on continuosly. As for the transistor, I don't have to much knowledge of such things but I'll take your word for it. I still have a week before I order so I'll take all this new knowledge into consideration. I guess I could always buy a seperate pre-amp in the future if I need one.

Yeah, good point. Is the pre-amp switchable on the 200P? There is three switches in the photo but I don't see any labels as to what each is for. Also, what transistors are used in 203 model and what is the rated wattage for these transistors. |

Dxuall, I'd say try a 28 amp supply just to be safe if you're going to use it as a base amp. |

Dexter30,
For help to determine what size Power Supply you need for Radios or Amplifiers check out the Article I posted in the
Subscriber (Preview) Area
» Articles
» WHICH POWER SUPPLY DO YOU NEED?
Hope this helps.

The KL-203 uses (3) RM-3 MosFets, they manufacture that part at RM Italy. I think they are rated for 30 or 40 watts each. |

Lon, I recommended that he use the 28 amp supply just to be on the safe side. I went to the thread you suggested and it read as such:
PR30 T70-00026, 28 amps, 6.25x6.25x10.25, 125 Watt Transmitters, VHF/UHF Ham Radios
The question I have is do you use the wattage listed for am tx or ssb tx when determining such a thing?
Thanks for the info Highlander. |

Dexter30,
The KL Web site shows input 12 to 14 volts and it pulls between 8 and 11 Amps.
So you always want to try and go bigger as you will probaby also be using a radio with it.
So a 20 amp minimum (FOR AMP ONLY) would work, But a 25 or 30 Amp Power Supply would be much better.
Always try and go as big as you can afford for future additions.
