RCI 2950, keys about 3 and swings to 15 or higher when I talk. I like the idea of the 667 because it has a driver. Some people say I can get more swing from a 500 though. Anybody have any experience with either of these. |

Audiophile73, Hello again sir, I have 3 Texas Star DX500's. They are great! I run one in the mobile 2 watt dead key 38 watt swing and I get about 120 deadkey and around 500 watts PEP! I run one on the base with a 2 watt deadkey and around 20 watt swing amp keys 120 swings around 450-500 PEP!
Your right the 667 has a driver pill. The 667 is a good amp for a low power single final radio. Personally if I was going to use a 2950 I would go with the DX500. The DX667 is not a good match for a dual final radio and I would not put any more drive 20 swing watts TOPS! And 20 watts is a little much for my taste. The DX500 could handle as much as 50 watts drive problems!
The DX500 and the 667 both have the same amount of output watts give or take a watt. They are just 2 similar amps made for different applications.
Kind of like the KLV-1000 and the KLV-1000P model amps. Both have the same output capability but are designed for different input applications.

don't bother setting up a driver to use the dx500 with your 2950. the 667 does it for you, no muss/no fuss. neither texas star amp is going to swing enough of a difference more then the other for anybody to tell the difference. when driven properly. your 2950 needs to key at least 7 or 8 to see 125-150 dead key from the ts500. nearer to 35 PEP to get around 500 PEP. it is more suited for the 667, if anything, you might need to drop the dead key a hair for 125-150. same for mic gain, if '15 or higher' swing is too much. |

your response wasn't up, 'wire, when i posted....i based my reply on audiophiles noted output from his 2950. BUT, i qualified my response with what the 2950 is more then capable of. in other words..... |

Right on Pat! Your expertise is always qualified big brother!
Audiophile, Read the words of Mr. Patzerozero all over this forum. He is an excellent source of info and I have gained a large amount of know how from this guy!
By the way, Reading my post above I need to make a correction.
"The DX500 could handle as much as 50 watts drive
NO problems."
Hope all this helps ya out Audiophile! Your on your way to one smoking setup!

Re: The Texas Star 667V
I have FINALLY found an amplifier that I am truly attaining the "specified" wattage from. Using my Bird-43 with a 1000H element, I was getting between 45-55 on the [bottom] scale (0~100). To be more accurate, I ordered and received a 500H element (also brand-new) and tested the amp at 45 to EML (needle pinned) on the 0~50 [middle] scale, which equates to D/K 450 (at 1/2 Var. Knob (TDC)) swinging well over 500 Watts. Of course, having the Astron RS-70M is a necessity, as it draws over the 58 amps as well.
I hope this REAL LIFE assessment can be of assistance to someone out here.

I have a galaxy 33hml on low it dead keys 1 watt on medium it dead keys about 3 watts and on high 10 watts swinging about 20 on each. I have the Texas star 500v in line, the tx500v is a high drive variable box meaning you can use it as a driver box just turn the dial a watt on and use the knob. With it being a high drive box you can run up to a 12 watt dead key (not recommend) and no more than a 50 watt swing. With a ten watt dead key you get 400 watts dead key out of the box but only swings to 500. With 1 watt you can get a 95 watt dead key swing about 550, I'm currently running 1 watt swinging 20 into the box has no problem with this setup. Ive ran this box with the 10 watt dead for several months testing it out it can and will handle the 10 watt dead key and not hurt your box in no way |

I have a Texas star 500 am driving a Texas star modulator into it dead key is about 3 watts and swing to about 40-45 the thing will swing about 600. If I true the drive off and just drive with radio,a cobra86 keying 3 going to about 15 I can only get about 300 out of the tx500. I was thinking I use do get about 450, my question is does driving the amp weaken the transistor like old tubes used to do. |

no, the cobra isnt nowhere near enough output
for the 500.the 500 can handle near 50 watts pep or [swing[]. i never used a mod v. but if the variable control controls dead key id try to lower it some. 600 pep is pushing the 500 pretty hard
