Six 2879's finals @ 100-125 watts ea = 600 to 750 watts PEP.

The Texas Star DX350 I have is rated for 300 - and it only has two 2879's. In reality - more like 275 watts PEP fairly clean.
So those numbers stated above should be a bit conservative...maybe s high as 800 watts PEP - with a good tail wind...

those 2879's only need 7-10 watts to reach their full PEP clean power .

look at the graphs on page 3 of the PDF . notice how compression and distortion are occuring as you drive it to its rated limits . i doubt it starts getting better or cleaner when you start overdriving it .

Booty..... there you go with your book experience again..... You are out of context with your info. We are talking about a (6) 2879 amplifier......... Not a (1 ) 2879 amp. a 6pill 2879 amp need more than ten watts to get full output

Full output is not nessecarily always a good thing.

Well... Don't know about you... but I want to be able to get full output from my equipment when I want. That does not mean I am going to run at full output all the time. From time to time I need to let my presence be known when I am making a skip contact and keep other big stations or big mobiles off my back. There is also a difference between Running at full output and over driving a piece.

A good antenna in the hand is worth 2 amps in the bush.

ok maybe you people didnt understand the question. i dont want to run a stupid motormaul, i dont wanna have to run another battery. all i want to know is this....is there an amplifier around 500 watts (plus or minus a little) that will handle 200 watts peak envelope?????? if there is not, dont give me the run around and a lecture about amplifiers. i dont want a 6 pill amplifier. the most i want to run is a 4 pill. if there isnt an amplifier that will handle 200 watts from a magnum s-6175, then just freakin say so. i dont want to have to turn down the radio everytime i want to turn on the footwarmer. if i cannot find an amplifier that will handle this radio, i guess ill just have to upgrade to the 600 watt PEP ranger, then i wont have to run an amplifier.

i figgured the OP could do the math and figgure out that it only take 42 to 60 watts max to drive that ammount of pills to their full output .
far far shy of 200 watts !! i wonder how clean they six are with 200 watts of drive ???

but......that rating is by the folks that did the research and development of the 2sc2879 and therefore invented the thing . but ....... what the hell do they know ????
they should fire all those folks and hire you to take their place since you know more than they do .

the difference between 200 watts and 500 watts is not gonna be huge or even pretty significant . you can put 200 watts to some of these 4 pill class C boxes and probaly see a kilowatt on a meter , but how many of those watts showing will be on the frequency your radio is TX'ing on ?

you have to decide for yourself whats more important to you .
a big (bragging rights) number on a watt meter ????
or a clean clear signal that isnt bleeding all over the place ????
then you will have your answer .
