    LD 1x2 ERF9530 mosfet

    Hello, By any chance do you have a schematic for building a amp using the ERF9530's? I have been looking all over the web trying to find some. My friend and myself have build a couple of transistor amps and a couple of LDMOS amps but of course we had schematics and full parts list. So if you...

    Cobra 2000gtl clock resets every time i turn it ON?

    I did this last year to my 2000. Rather than using a cheap vacuum sucker or wick i went on Amazon and bought a 30 watt desoldering electric vacuum solder sucker for around 35 dollars or so and i did all the caps in the radio and It was so EASY with that tool. I have always used the two others...

    Band-switched SS 500w amp on eBay, Homebrew - nice pics

    Well MANY amps on Ebay get pulled. If they can be used on 11 meters for sure they get pulled. Depending on how the ad is worded hey get pulled unless they are stated ham amplifier and it helps to say not for CB.

    Amplifier for SSB

    The pre-amp amplifies the incoming signals to help pickup weak signals. For most people they normally are of little help but sometimes they are helpful. P.E.P is the output wattage under full modulation/audio, VS your base dead key. This is a very simple explanation.

    Replacing the Potentiometer Texas Star DX667V

    Thank you for the response, looks like 2 watt is as large as i can find and most of them now are made of cermet. And from what i read is very much like metal film. So i guess i will see how the cermet 2 watt potentiometer works in the application.

    Replacing the Potentiometer Texas Star DX667V

    Thank you, i knew that i had read that wire wounds were not to be used around RF/radio. Spec is 2 watt but as it has failed my thought was to bump u the wattage just to be safe and i would hope last longer than the failed one. Guess i will stick to the 2 watt ones that were easy to find. As...

    Replacing the Potentiometer Texas Star DX667V

    Question for those who know more than myself, The variable on the DX667V calls for a 100ohm 2watter. I plan on using a 5 watt version but should i use a regular carbon type or a wire wound? I know that i have read before that under certain uses wire wound should not be used. So do i order...

    Just picked up a old Texas Star DX667v

    So as the title says i just picked up a old Texas Star dx667v and i have a nice new 150amp variable power supply. My question is what voltage should i run it at? If it matters it uses non red dot toshiba's and it seems to run without any problems. It does have a 120mm fan kit installed under it...
