    Years back there was a site on the internet that showed how to remove the final on a galaxy/connex and replace it with a 2sc 2290. Did anyone happen to save that info? It does not seem to show up anymore.
    Thanks

    Google turned up some dead links to a "customcbradios" forum.

    Here's a YT from a guy who did it the hard way with a DX959.



    Looks like he borrowed the final section from a Stryker.

    Nomad. I remem
    ber that one There was also one similar to the conversion done on a hr2510. At one time somebody had also copied what was on the internet and was selling the plans on eBay that is all that happened to show up I am hoping Sonoma copied the information off the internet.
    Pardon all the errors I am doing this from my phone and forgot my glasses

    What a waste of time to do that, just buy a 1 pill driver and you'll be way better off.

    I would just buy a hp40 but do not want the to run the 10g wire from the battery. Not sure I will even do this. It is a idea though.

    Sonoma I think I saved it on my old computer that crashed.
    Thanks.

    Thanks Sonoma, I will put this in my note book. I have one question though, how do you determine what the SWR is between the 1969 and the 2290? if the 2290 was a separate amp then an SWR meter would work. Just wondering how to know what the match is between the stages. I have a Stryker 440 with a Toshiba pill in it, I will have to take another look. THX

    Sonoma.
    Here is all that I came up with was a part of a listing that someone copied and then sold on e bay. You did not have any other pictures of the finished job by any chance?

    Low Boy I just finished going through all my saved items and do not have any thing else.since I never really tried this mod since it was so costly I guess I did not even save any more than the one page I had.
    I did do one radio years ago since I had one pill to try it on.. that was about 20 years ago.
    maybe some one else will have more.

    Connex4300AdapterboardReference.jpg Well if the concept needs a little help, I've done this up to help someone - got laughed at so I never pursued it any further.

    From a Connex 4300 uses a 2290

    So at least you can see how a daughterboard can be done up...

    Andy that is the radio that got me thinking about all this. I fixed one for a friend at work and could not believe how smooth and nice sounding that radio was.

    Low Boy that was so long ago. I think I only got about 60 watts out of it. was not real crazy with the mod so never tried it again. I was getting about 30 to 35 out of the radio I did it on and not much of an increase. easier just to put a KL203 amp on the radio.
