And his reply;
A little history on that meter..It was given to me by a buddy's widow shortly after he died...prior to his death he had sent it to Dosy to have it re calibrated, I know for a fact that he had never used it after he got it back, and this is the first time I have used it.
Bummer!, but at least I know what the root of the problem is.
Anyone want to buy a Dosy? I am only the second owner, might be willing to trade for a bird....

Ok I have a galaxy 33hml on Med. Its doing about 2.5 swinging 30 I get a 400 Watt dead key swinging to about 725 out of my Texas star 500hdv I was running my radio with about a 10 Watt dead key into the box and it took every bit of it with no trouble other than heating up the box really good I suggest a 7 Watt dead into the box is good enough it should give you a 450 to 500 Watt dead key.
op:
is it possible for the varible pot to go bad in these amps? yesterday morning i went to turn down the linear with the knob and as soon as you back it down output drops to 20w..... guess it needs a new varible pot on the front... what is the value on this pot?
100 ohm 5 watts.
Leave it wide open and use the radio to control the power.

Well I've been running it this way way for three months and no problems out of it. Its been doing great. I was 20 to 30 miles from home talking to my local guys at home and they swore up and down that I was in town but I wasn't. I'm currently using a 2.5 Watt dead key into the box and getting a 400 Watt dead key swinging 725. If the box is a high drive box it should be able to handle a 500 Watt dead key as it is stated to do. Ill find out, and besides the 2879's ain't that expensive if you shop around yeah you get what you pay for bit its fun to kinda play around.
Lol
3.5 to 4 watts in will net about 200 to 250 out
20 watts peak in will get you about 500 watts out
The basic T/S 500 V has not changed since the 80's
2879's are running about 35 bucks each nowdays.
I am not tring to bash you but if your meter is correct ( and I do not think it is) a 500 watt dead key is way to much for a 500 v. I would not run a class c comp amp at 500 watts dead key if I wanted it to last very long.
X Force recomends no more than a 300 watt dead key out of the 400-12 and it is running 4 2879's in class B
If you want to keep that amp happy stay under a 200 watt dead key and let it swing up from that. And put a fan on it.

i had a 500v i used with a uniden washington with a variable deadkey . the variable on the amp was scratchy but i just bypassed it with the green button and 1 1/2ish watts gave me a 125ish deadkey , the 16 pep the radio did would swing it to half a hair under 500 watts . the variables are known to go bad in them but they are good clean CB amps .
What he said. ^^^^^^^^^^^^
My 77HML only does right at 20PEP and that's exactly what I'm getting.
You expect people on this forum to believe what you posted?????? You are lucky to get 500 watts out of a TS 500 driving it with a ModV. Only 3 posts on this forum and you are already being asked to sit in the corner.
Now thats just plain funny right there.....wow. Sounds like someone needs a new watt meter for X-Mas.

and someone has no idea what a proper dead key to swing ratio is .
but , some folks just wanna see their meter swing to the right as far as possible all the time .

@ Geoexplorer69:Coax question. I just put up a new Sirio monsoon base antenna with 100’ of rg8u coax testing with myMFJ antenna analyzer shows 1.4 swr at 26.965mhz and a 1.1 at 27.405 mhz . When I checked the ohms it’s steady a 30 ohms across the entire bandwidth.
