Ok I have a galaxy dx-2527 with the EPT295013Z board and im wanting to swap the finals to mosfets. Can anyone please tell me what is needed to do this or are they just a drop in.

Galaxy dx-2527 mosfet mod

Don't understand why you're wanting to butcher a working radio... to each their own i guess
After looking through the mod sheet at Bennies site, it says that it's not recommended to put mosfets in the 2527 because of power supply issues, but the mod is still shown.

Basstracker:
I think QROdx pretty much made the right point. Even if you put these MOSFETs in the radio, the power supply in your radio cannot support the amount of extra current that these devices will require/draw. Your power supply will presently only provide about 5 amps continuously. If your radio has an external 13.8v source and a switch to use an external power supply, you would need to get a power supply that can handle about 10 amps @13.8v. You can't get something for nothing . . .
Not to mention, that if you have never done this kind of mod before you may too easily get it wrong. I say this because you said 'are they a drop-in replacement'? No; they are not drop-in replacement. Not really for a beginner to do. They also need to be properly adjusted and even require additional cooling from a heat sink with perhaps even a cooling fan. A Cobra 29 or 25 is an easy place to start for a MOSFET mod - IMO.

Ok guys I won't do the mosfets I will just do a swing kit. All I do know is that this dx2527 won't drive my KL503 nearly as hard as my dx-959 mobile did with mosfets in it. The dx959 was doing around 300 and all i can get with the dx2527 is 200 w.
honestly, i have never had a base that would do as good as a mobile.
Years ago, I thought that it might be the power supply, so I turned the voltage up to 15V on a midland and it made a difference in output but still not like the mobile with identical board on 14V.
Even went as far as disconnecting the built in power supply and hooking it up to a 20A, and even then with tuning, it just wouldn't do the job.
I would say that you might "bump" the supply voltage just a little bit BUT I would be very cautious about trying it on that radio since it has already been stated to have PS issues... thinking about it most of the rci/galaxy bases did have PS issues with the worst one being the original saturn turbo

if you don't have anything good to say then don't say anything, ok?
I have added mosfits in a few of my mobile rigs and yes they do make the radio louder by quite a bit.... Some of my customers can agree with me as well...

Its called trying to convince yourself all the time and money wasted did more than just adding a 40W linear did.
So if you're convinced you are correct perhaps you can give me a technical explanation as to why?
