Rack mounted Texas Star DX 1600

[akzo1990]

Here’s a link to my newest homebrew project. This amp will be used with my homebrew power supply in the earlier post. The cabinet that I used is a decommissioned Harris television transmitter remote control cabinet. My dad retired from this television transmitter site and has a lot of neat stuff like this around. The boards are from old salvaged Texas Star 667’s. The smaller heat sink in the picture will hold the driver. I plan on putting an amp together like the new DX399 so that I can keep the same switches as the 1600. Let me know what you all think.

Nice looking setup! I like how you mounted it in that cabinet. Looks nice and clean. How many watts is it going to do?

Thanks for all the nice comments. I now have the DX399 put together and mounted in the cabinet also. I’ll try to get some pictures taken and added to the album today. The 1600 is producing around 1200 watts dead key.

"The 1600 is producing around 1200 watts dead key."

Why?

if only i had a welder. Oh the things i could create!

Hey Freecell,
My 1600 is producing 1200 watts dead key with around 100 watts of drive. Do think that I should be seeing more output? I have not put the amp on a pep meter yet as I'm sure I'll see more output on it.

that's great for fm operation but you better back down the drive for am. peak-to-carrier on am should be 4:1 for 100% modulation.

300 carrier/1200 pep am would be ideal. rock the house.

What kind of antenna are you going to use with that monster of an amp?

Why do you want so high of a deadkey???
1200w DK from a ts1600 is way too high!!!
400-500W dk SWINGING forward would be much better
And keep the amp WAY cooler..

AM POWER

Actually this was done for testing purposes only and will not be the normal operation setup. I wanted to test the power supply that I built for a continuous load. The power supply has done fine so far and the load was around 126 amps.

I plan on putting up a Lightning 4+ by Signal Engineering and that will be the antenna used with this amplifier. Another project for this summer

ok so if you had 1200 @ 100 watts in you probly want to set carrier to 25-50 watts. for am talking.

unless your egtting some major swing above 1200 watts withh 100 att carrier. but i doubt it with a 8 pill TS.
