    Texas Star is also for sale. Its doing 300 watts RMS, almost 500 PEP. Better than my DX500 with DEI pills.

    Yes, I am aware. I was setup for the 2879s by my uncle. An electrics/cb tech of many years. Its working great and for sale on ebay.

    DX400 no transmit.. no preamp

    I got this "Texas Star" and a Super Star 250 for a good deal. The 250 had a bad pill. Ended up throwing some Toshiba 2879s that were laying around in it. Works great now.

    DX400 no transmit.. no preamp

    Nope. It might be an old school TS, but doesnt say it anywhere. Says Bi lateral DX400. Yeah its working great. Maybe, not sure. But its working great in the mobile. Maybe im having issues with grounding.. Some weird stuff has been happening at my office with power supplys and what not.

    DX400 no transmit.. no preamp

    Ill check them out again, but i didn't see anything notable. This amp looks like it was never used or they were easy on it. Picked it and a superstar 200 for $100. Its not actually a TS but a copycat. Pretty close too. It works awesome though.

    Sure thing. Gotta fire the crane up tomorrow and take down the antenna. Have new coax anyway.

    DX400 no transmit.. no preamp

    Well.. This is dumb. Figured out the issue.. I think. So I noticed that the bench radio didnt have very strong receive. Normal people I talk to were pushing half what they normally do on the meter. Checked all my jumpers, no issue. Checked my SWR with my antenna hooked right in, it was sky high...

    DX400 no transmit.. no preamp

    Got to plug it in today. It died while keyed up. Preamp working, turned it off, keyed it up and the relay clicked on then immediately off while still keyed. Then i tried the preamp and it made recieve fade. Hm

    DX400 no transmit.. no preamp

    Well, that diode was open. Replaced that and the transistor(again) and started checking all the other components. We'll see. I had other work come in and was unable to test it. REALLY bugging me. I need to set up a work desk at home! ha.

    DX400 no transmit.. no preamp

    I also don't really care for the preamp, but I am hoping its a "clue" since it stops working when it won't key anymore. Will be heading to my office and starting to check more things out in a few here.

    DX400 no transmit.. no preamp

    I know. Just figured I try find out what the common link between no keying up and no preamp is. Thanks.

    DX400 no transmit.. no preamp

    Thanks. Was going to start checking diodes in the morning. I am a mechanic and specialize in electrical diagnosis, but just now getting into CB and ham radio, so i am unfamiliar with these specific systems. So i do have all the toys to test stuff. Will report back in the AM!

    DX400 no transmit.. no preamp

    Hello all, first post.. I have a DX400 amplifier that is doing some weird stuff. Just want to get some opinions. Picked it up very cheap, cleaned it up and hooked everything up. Was making great power, no issues. One of the fuse holders was kinda funky so we took them out and upgraded all the...
