All black fatboy 2x2290 amp

[capone344]

Hello everyone. New to the forum here. I can't find any info on this amp. I got a black fatboy 2x2290. Can anyone tell me anything about it. I don't want to kill it. My galaxy is dead keying 3/4 a watt and swinging close to 60. I got a blue face palomar 225 that like it alot. Any help would be appreciated

I'm not quit sure what the palomar had. I'm thinking 2x1446. I have the amp deadkeying aound 30 watts and swings around 200 on medium.

bing fatboy 2x2290 amp and see if it will help show you some info.

Yep, "Google" is your friend, since I have never seen a FB in black I guess someone customized it.

2x2290 Trucker
Requirements:
• 2-5 watts of drive
• Intended for single final radio
• 1.5-1 or less SWR recommended
• Boxes are tested through 12-16 volts
Specifications:
• 300 watt PEP average at 14-15 volts
• 85 watts RMS at 14-15 volts
• Amperage: 14 Amps
• Dimensions: 6 3/8" x 3 5/8" x 3 1/8"
• On/Off power switch with LED
• Contains variable output control
• Stainless steel hardware
• Brushed aluminum finish
• Vented from both sides
• Rubber vibration feet on bottom

Don't think there is a whole lot more to say about it.

Fatboy used to sell the black trucker amps when they had amplifiers on their website. It was their economy line. No cooling fan or any other frills. If you want it to last I would take the power rating of 300 watts and cut it in half. Set the radio to get 40-50 watts deadkey out of the amp. If you talk a lot keep an eye on the temp and add a fan if you need to.

Thanks all for the info. Another question. What MdYoungblood found states it's for single final radios. Would my galaxy dx29hp dual final radio be overkill? I'm just getting back into the whole scene. I used to have a galaxy 88 matched up to a Palomar 300hd years ago. Should I just unload the Fatboy and keep the Palomar 225, or the other way around? I'm strictly AM. Don't know which would be better. Thank you army1975, 543FtWorth, and MdYoungblood.

And the Fatboy does not have variable power, stainless steel or brushed aluminum. That's why I don't think its a trucker. It actually looks like a Texas star modulator. Heat sink on the bottom, top cover extends over the front, 4 screws cover comes off. It only has a low/high rocker switch on the left and a on/off rocker switch on the right. It should be here Saturday. I can post some pics and more details once I get my hands on it.

I would listen to what 543 is telling you and run that amp as suggested. 40-50 watts carrier max out of amp. This may take anywhere from
.1-2 watts of DK. A single final radio is what is needed. Your radio at 60w pep is way too much drive for this amp. That is enough drive for a 4-6 pill amp. Way too much for 2 2290's if you plan on keeping the amp for long. Add a fan and keep the power levels to about 150w or so and it will last. JMHO.

I'll probably just unload the Fatboy then. The Palomar is working good with my setup. I like that the Palomar only draws 12 amps in the work truck. I slip seat. I figured a Fatboy would be an upgrade for me. So would the Fatboy be considered a driver then? Lesson definitely learned. Again, thank you everyone for the input.

The amp I'm getting is the same one that is in the Fatboy 150/300 topic.

[MDYoungblood]

Hitting the Palomar with 60w PEP is a bit much too. I would put the realistic figure of the FB at around 200w PEP with a DK of 40-50w. All in all it is a better amp than the Palomar, those 1446's have to be getting tired.

Ok. So adjust the deadkey for the fatboy 40 or 50 watts out of it. But why instead of 30 like I had for the palomar? Not being smart. Just trying to understand everyrhing. Thanks for being patient with me.

If you're referring to the post that I posted about the Fatboy 150/300 check out **Censored** Amps YouTube video titled "Fotboy 1446 2 pill". I sent him my amp to confirm that it was in good working order before taking a chance on damaging my radio since I'm new to using an amp.

[capone344]

I will check our the video in a few. Mine has 2x2290 in it.

I just gave you a 40 to 50 watts as a safe limit based on the transistors the amp has. You can run less if you want. Some people run them a lot harder but I don't recommend it.

[1206FL]

Again, listen to 543. I personally wouldn't push that amp beyond 160w pep max. And that is with a 40w carrier max as well. You want a 1:4 ratio of power or close to it. So if DK out of amp if 40w, then pep should be about 160w. At 50w DK you'll see about 200w pep, or should. But you will be pushing the amp as well. And with no fan and a small case like you're amp is built in, you may want to add a fan to it to help keep it cool as possible. Also like I said, it make take some drilling of holes as well to help with the cooling. Look at the way the TNT 350hd amps are built for some ideas as to what you can do to help with heat, especially if you are going to run it at 200w or more. JMHO. Are the transistors DEI or Toshiba 2290's? If it's got DEI transistors then I wouldn't push the amp too hard. Again this is JMHO. But really a single final radio like a cobra 29 or any other single final radio will push this amp just fine. JMHO's. Have fun with it and don't let the magic smoke out!!

That palomar probably has a pair of 1446's. That Fatboy with 2290's hopefully Toshiba. Neither should be driven with more than 20w pep for long life. Otherwise prepare to spend money or scrap it if you blow.

[Deleted User 14541]

The cobra 25 or 29 is like the AK-47 of CB radio. When you absolutely, positively, got to kill every duck in the room. Accept no substitutes.

Anyone else see that movie?

[Crusher]

Lol, the Cobra 25&29 are good radios. But I love my old 148's and Grant XL's.

[capone344]

Thanks for all the input everyone. I opened the palomar and to my surprise has mrf455's in it. Thought for sure they would be 1446's. But the fatboy has the Toshiba 2290s. I'm not really hitting pep every time I speak into the mic with the radio. I'll keep an eye on the temp and if I have to add a fan. I don't talk to long and only use the box when I talk to my contacts when I'm working.
