Texas Star DX667V, all Toshiba's. It takes near a 2w deadkey to key it up and by then the amp deadkey out is 180w, so using the variable to tame it back to 120'ish and the swing is the expected 500w PEP. I was told it could be the relay is dirty, so I cleaned it, still the same thing. My...

Just replaced an old Taiwan Cobra 148 GTL's speaker that was getting raspy sounding at low volumes with a brand new Workman SA-350 3.5" replacement speaker, did the trick. The old speaker has a small cap across the terminals, (see attached) and the new one doesn't. Does anyone know the reason...

What would be the max AM RMS output I could run with a less "swingy" radio with a Texas Star DX500V? I'm picking up a Yaesu FT-891 and not only do they do a 5w minimum carrier on AM, they really have no swing, perhaps a 1-to-2 ratio vs what one would normally use like my 148 with a 1-to-4...

Is there any change in the AM deadkey input limit for the RM Italy KL 503 HD vs the original KL 503? I know for the non-HD version its 1-2w and low swing and for the HD version they say up to 35w, but no mention if a higher carrier can be used. I believe the only difference in the two is the...

I have a President Lincoln II+ V3 radio and love everything about except one thing, and its a biggy since I like to use the radio for scanning memory channels. The Squelch on AM is terrible, ASC is even worse. When I receive most any signal and no matter the signal strength, the squelch opens...

I just picked up a clean Toshiba loaded Texas Star Black Widow - DX 350HDV, and while SSB is perfect, the AM side has issues with AM carrier output. Even with my radio at 1 watt with the AM switch out, the carrier out from the amp is like 150+watts. With the AM switch in, its more manageable but...

Is there a list of the what the President Lincoln 2+ v3 adjustment locations do? Looking to boost the SSB watts, adjust the AM watts both high and low and peak the modulation. I did a couple of Google searches and figured it would come right up but nothing. Thanks!

When using my Texas Star DX-500V wide open, just power on, (no SSB delay or AM/Dial A Watt engaged) radio set to 2.5, dkey so amp output is 100w dkey and swings up, the SWR between the radio and Amp runs a little high via the SWR meter in the radio (stryker 955hp) from 1.7-2.0, but the SWR after...

Hey there, a question I don't think I've seem come up, how many watts can I put through a Texas Star amp (or most amps) in bypass mode? Is there a way to tell if not stated? I have a Yaesu FT991A radio that I use with my 667 on SSB, running 10w PEP, puts out a nice clean 500w PEP. Flip side is...

I have an older nice and clean DX 667V with Toshiba's and no output, but everything else seemingly "works" as it should otherwise. I followed some of the steps here in this other thread and got as far as I could in a short amount of time...

Does anyone have any techs they can recommend for repairing Texas Star amps?

Hey Gang, Just picked up an DX400 off eBay, its an old Bi-Lateral with 4 - SRF2072 trannies and has 3 symptoms. The good, the power output seems fine, driving it with 1.5w's with AM button in out's 100w carrier and 400'ish with swing, just like it should. That's where the good ends. - When...

Looking for an amp that I can use with my Yaesu FT-991a and Icom 7200 for 10-11m use. Sadly the Yaesu can't go below a 5 watt carrier (way to much for my 667) and the Icom sounds like ass when run below 3-4 watts, so looking for something I CAN run even a 10-20W carrier into and not blow it up...

Kind of a newbie question, new to the whole amp thing, and I'm running a Texas Star 350HDV with Toshiba's for AM & SSB, works great on both, I don't over power it, old school Cobra 148 deadkey at 2w's, swing to 15, SSB peak about 20, works great running with my Astron 50amp, MFJ-948 300w tuner...
