What's the maximum voltage the Texas Star DX-667V can handle? Also what's the maximum output of this amp, given a 4watt drive AM, 14watts PEP SSB?

You asked max voltage, answer 15v.
You asked output with 14w of pep or ssb drive, anser 550w @ 14.5v on a Bird 43p. Bird 43 rms watts about 275.

I am thinking of getting a 667, and running it on a 2980 WX. What dead key, and swing should I have, and what size of power supply do I need to get? Is it gonna be somewhat free of tvi and rfi at lower power? How 'bout at the higher power? Since I live in a travel trailer with a 20 amp circuit service line, do I need to put the power supply on a seperate breaker. Am thinking of using the breaker for the old roof a/c unit. Any suggestions will be very much appreciated.

the 667v will perform best at around 3 watts dead key input, & less then 18 watts PEP. though, you will have to experiment a bit to find the best settings. you should see about 150 watts dead key & 500 watts PEP-with sufficient current supply. a 50 amp PS will probably get you FAIRLY close to full power, though a 667 could draw closer to 60 amps. the PS under full load will draw 12 or more amps, so it would require its own 15 amp line, 20 amp line with the radio, lighting, etc should be alright. is the roof AC 220v or 110?

as for what kind of rfi you may cause, it depends on MANY things, so a guess as to your troubles is impossible to make. any amp, in a base, with other homes nearby needs much care to reduce interference.

The air conditioner is a 110. The breaker is a 20 amp breaker, but says 16 amp max. Sounds like this isn't gonna be an option for me. Don't sound promising at all. Guess I'll maybe need to go with something smaller, or just get the 2980WX peaked and tuned, and just be satisfied with being barefoot. Darn the luck? Thanks for the help.

you could just use the 667 LOW...use the amp on any 15 amp circuit-just don't turn anything else on at the same time if it can't be on its own dedicated line, except a lamp maybe. the radio probably draws just a few amps at 110VAC, maybe 3 or 4 tops, so it could run on a circuit with several other things.

Before I went to a dedicated 15 amp line my power supply at full power and a hair dryer toaster or similar tripped the breaker. Going dedicated is VERY important so you get no volt drop.

Pistonpopper! I have heard a lot of good things about the 350Z!

Pistonpopper,
Instead of A 667 think about this. Buy the TS500 and a TS ModV. The ModV (driver) will give you the power for local rag chew and when the skip is running hit the power button on the TS500 and have fun. This setup up give you lots of vesatility. You can control the Deadkey in the TS500 better with the ModV and you wont have to run a 52 amp power supply wide open all the time just to ragchew to your locals. And I'd bet the TS500 and ModV combo will run right there with a TS667. Just one more thing to think about!

You guys crack me up! My radio room which used to be a garage is next to the kitchen and used to share the same cicuit. Actually I have a coffee pot, microwave, apartment size fridge full of Dews and a waffle maker all with easy access in the shack! Been thinking about putting in a bar and jacuzzi for the ladyzzzz! I can see myself relaxin in the jacuzzi while making CEF contacts. Just gotta be careful not to drop the mic in the water or the ladyzzzz will go home!

Thanks guys for that info. I am thinking of getting a base transistor amp that draws about 15 amps, so that I can run it off the circuit breaker for the old airconditioner circuit. Any ideas?

I guess I'm havin a problem reading between the lines Pat, what do ya mean that my neighbors will love me? Is the X Force not a clean amp? Will check them out. I have an RCI 2980WX with a 3 watt dead key, right now, and swings to about 10 watts!

the xt40012 should get you about 300 watts or so dead key & around 1200 PEP with the 2980. as for 'dirty', no more so then pretty much ANY other CB amp. keep a well grounded & (tvi) filtered clean, unclipped signal from the radio going into the well grounded (& filtered as well) amp, & you have a chance of keeping it a secret from the neighbors.

Out of curiousity Pat, how would I filter the amp, even though I have a Vectronics low pass filter inline already? I will not have the 2980WX clipped or modified, just peaked and tuned with maybe a lower dead key and try to keep the swing at a "bearable level! Maybe I'll look around for a good used xt40012.
Thanks and cya

search this forum for grounding & rfi prevention info, in particular pics of tech 808's station, & info from tech 833. not clipping/tweaking the radio is the 1st step to a clean signal. then place a quality lowpass filter immediately following the radio. grounding ALL the equipment & antenna is next. another quality filter after the amp can't hurt either.

that amp is gonna SWING! no matter what. reducing mic gain, even in AM, will lower it. don't use the variable knob on the amp(if what you get has one), reduce dead key of amp by lowering dead key of radio(that's why a variable knob on the radio is a nice addition).

Hi pistonpopper, A standard 110-120 volt outlet will supply a DC 13.8 volt power supply up to 50-70-amps in output size. Depending on the breaker size a 15-amp breaker is probably going to have an AWG no.14 copper wire coming off the load side of that breaker, and a 20 amp-breaker should have a min. of a no.12 AWG CU wire from it's load side. I have an outlet(the 20 amp recpt. type)with a No.12 AWG CU feeding it and run a tripp-lite 50-amp PS another 7-amp PS my Base and sometimes an amp idleing with a string of 8950's in standby all with no breaker tripping. I have used an amprobe when keying down with everything on and it reads 16-amps.

AK3383, what ya'll are saying is that with a 20 amp circuit breaker, I could use a power supply or regular base transistor amp that would need between 50-70 amps output. I think that I am just going to get the 200 watt Cobra amp. It's a base transistor amp. Am gonna use the old airconditioner circuit for an appliance extension cord, and hook the amp up that way. I could probably go with a bigger amp, but I am afraid of bleeding over on the neighbors. Will eventually get an amp for the mobile, and that's where I won't have to worry about bleedover!

Is a magnum S 680 set on 2 watts to much for a 667V texas star amp

the swing alone of that radio is too much drive cause it has a built in driver already . a cobra 148grant works much better. for a magnum s6/80
a texas star 500v is more suited
