it's a clean 200 -250ish watt pep amp . they run a little under $300 . if you want more power a TS 500v is about $400 and will do 500 clean watts pep . bothe will need to be converted for modulated signals , but that's typically included for those prices .

Look into the TNT line as well 351, the 600HD would work well with your setup IMO, and not be over driven. That or get a straight 4 pill xforce. Leave the 1 pill driver stage alone, more problems. I see that the bottom amp says high drive. Well it's not as it has a driver section already, and the midnight specials don't do well on ssb as they are a class c amp. The TNT amps are biased b, and I believe the xforce amps are as well. If not go for the TNT line. Like I said the 600HD with the grant 2 behind it should produce 4-500 clean watts. And not be overdriven. This is JMO. Ask around a bit. God bless and hope to talk to you soon on the air!! 73's mate.

Thanks 222... I like the texas star 667v if i can't get it hear or its too hard, i will look at the x400 like in pic above but they have low and high drive same as above .. Its a 5 pill , tell me what you think of it, the x400m that is 222 .. You obviously know a bit more than me about amps mate, slight different number for the low drive one... Can you have a look at xforce site at details.. I would hate to buy wrong one and miss match.. Cheers 222 :-)

The Texas star 667v is a good amp too, I just like the new TNT line better. Get one with real toshiba 2879's and ssb delay and I promise you will get good reports. Same amp is what I am running basically, mine is a 2 pill magnaforce 350hd, same as the TNT 350hd. Good for 200-350 clean watts. The midnight specials are biased c or class c amp and not very good for ssb use. The xforce m400 may say hd, but I promise if there is a driver (5th) pill, it is a low drive amp. Not that that is bad, I just prefer to stick to amps with no driver section, less to go wrong and with the straight 4 pill you can put some watts into it without ever overdriving it. JMO ask around maybe ask tallman his opinion as well. God bless and hope to hear from you soon.

SSB delay can be added if necessary. Cant go wrong here and it will keep it's resale value. This will run off your stock charging system as well.

What's a Dave made 600 800 worth. ? And is it 13.8 v ?? Looks bit like the xforce..

03-20-2014, 05:32 PM
Tallman has helped me lots 222 he recommended a Texas star but also likes the force... waiting to hear what he thinks of the low drive x400m... :-)

Yes the Dave made is actually the original amp that a lot of people have copied. Including xforce. They are great amps!! Didn't even think to mention them but they are top notch!!! Gordon is right on track!! Thanks sir I had forgotten about the Dave made's. They are expensive but worth every penny. They are a little more expensive then the xforce amps 351. Google Dave Made amps. They have been around for a long time.

The force x400m starts at 400 ish and soon gets to $630 with good biasing and pre amp, mod lights ..that gets it to $630.. But it is 1kw 1100 watts... see what Dave wants for his and I will let you know how many watts for watt lol...
2year warranty sounds good.... cheers Gorden... I try'd to ask you before but you were gone ! .. 351..

Why do you need go waste money on garbage like a preamp and modulation lights? Trust me, gay lights won't get your signal out any farther. Theres no reason to consider anything larger than a 1x4 for daily talking. A 1x4 is about as large as you can go on a stock charging system. Unless you drive something fruity like a Prius or some other tree hugging ween mobile. In short a 1x4 is perfect for you. You can even go as small as a 2 pill and still have great results. Keep away from the stupid gimmicks like lights and stuff. The only addition that might be practical is adding a ssb delay if you talk sideband.

With out all the fag shit Gorden I use a Grant 2 at home as a base, I drive it with a home made solar system that has 4000 watts available at 240v all day everyday, it has a power supply driven from it that soon will have 80amps just for linear amp, there is also 24v big bank that has 60 amp step down to 13.8v... The reason I've ticked the box for "fag lights" is to get a price with all the extra bits , don't really care for power wasting would rather be on radio longer... 351 ...

If you click on the link you will see prices. And yea, multi-colored lights that blink with modulation is gay. Very gay. Its Justin beiber gay.
Although the power consumption is negligible, for the same money you could have added ssb. The lights is just an example of Carl at xforoce cashing in on peoples stupidity. Why doesn't Fatboy or davemade offer these lights? Ultimately its your money, just try not to get sucked into things that aren't necessary.

I don't know Justin, but I did what the per amp because I live on an island off Australia and some only some type's of pre amp do help with out just making it louder , I don't know the difference between the two as far as how they are made.. Thanks for the help and advice ... It is needed this way... cheers...351

I need to understand bias and what it is and about any filters that help with clean audio or longer life for unit, was thinking buy bigger than needed with variable power to run it not flat out, Will this help life of unit ?
Yea stuff like that this Aussie needs to know, and no offence meant to your friend Justin, Just have not been hear long and have not come across him... Cheers.. 351 :-)

351, Dave made amps are what xforce and most other companies that build amps have copied. The Dave made amps are great amps, just didn't cross my mind at the time as there are so many options these days. Look at the gold box Dave made's, they are worth every penny. And as far as biasing goes, a/b, or class b are good for ssb, class c amps are more for am, less filtering. The better the biasing a, a/ b, b, c are classes of amps, a or a/b biasing being at top and b biasing being 2nd or 3rd. Class c amps are normally not used for ssb. Get at least a biased b amp for ssb. As far as the 1x4 or straight 4 pill, it depends on the radio. The grant 2 will work well with a 1x4 as Long as you keep the pep watts to around 20 or less. A straight 4 pill won't put out the same numbers but will last forever with the grant 2 being used and if you ever decide to step up to a dual final or more powerful radio you have some headroom with a straight 4 pill. It's a matter of opinion maybe, I like boxes with no driver section as I use more powerful radio. Go with what suits your need the best and also keep in mind about future purchases of radios. JMO. The Dave made amps are good, xforce and fat boy have basically copied the design and made their own line up. The Texas star amps have been around a long time as well and are a good amp. Like I said, some of it is fact and some opinion, do your homework and buy what you like. God bless.

All a preamp is going to do is make the static louder.

solarradio351
03-21-2014, 03:56 PM
Again thanks for the info guys.. still learning this way.. noticed the force is c class but then you add$$ for the biasing to have b class I think ? Is that how it works? Look at xt400m for me .. any good.? Gonna have a look at this gold box... cheers

222DBFL
03-21-2014, 10:04 PM
Yes, get at least biased b, if you can get a/b biased. Preamp is up to you but as said, it just brings up the floor noise more. It may help it may not. I don't use a preamp, if I can't hear you I probably can't talk to you, but I have used pre amp on another amp and had success, it's all about the filtering. On the tx and rx sides. The m400 is a good amp, look at the Dave made 1x4 as well, before making any final choices.

Cheers 222 and Gorden.. will put a bit more homework into it before ordering this one, The last pre amp was a waste of power , my dad had a old school one that was a little ripper, just seemed to make voices louder and not all the background noise ... have ordered new IRF540's to have a go at a home repair, also might get smaller amp for the 4x4 I can use it till new one is sorted.... I am still a bit stuck on Texas Star, If not the Dave Made would be my choice ... Thanks again for helping out ;-) I have picked up a bit more information I never had a clue about... Fruit, Farming and Land management that's my field ! Lol...... Thanks.... 351 ..Come eat a Tassie apple ... :-)

A good 2 pill will get you out just fine, it's all I use. That and a magnum 257hp. I get around 300-400 watts and it's clean so I have been told by many. My amp is an old xforce built 350hd 2 pill with 2 pre red dot 2879's, biased b. high and low switch and ssb switch. And a large fan on top, it works well even with my uniden PC122XL I got reports from hams that the audio was top shelf, got ideo gated on classic radio roundup on dec 4, while in the Baltimore, MD area. Anyway a 2 pill will work well with the uniden grant 2 and will get your name called, it's all about antenna system and conditions after that IMO.
