on that T-600 (which is apparently a version of the phantom 500) - it has been set up for high drive? is this the best way to drive an amp? if so how many watts should i bee driving it with? any recommendations? my repair guy says he can redo the drive circuit if we can find a schematic for it. |

high drives are excellent.alot of times people dont drive them enough and they dont perform.i dont put anything less than 15watts of drive in my taxas star high drive. if your radio has at least 10 watts of dead key you'll do ok i put 20-30 watts in my high drive from my 2990. however if your radio only does 4-5 watts deadkey it wont drive the amp very good.if thats the case i would change the cirits to low drive. or get a texas star mod-v their perfect for driving high drives |

I'd sure like to see a Texas Star (factory stock) that would perform well with a 15w or larger input carrier other than a DX1200 or 1600 |

10 watts dead key i think woulda killed my ts 350hd if it didnt kill it it just wouldnt sound good you must be just talking bout the 1200 1600 amps but you didnt say |

Ummm i dunno if id run that TX star amp with that much carrier. I always ranned my TX Star 500 with about 3 to 4 watts carrier swunged to about 30 or so and always got good audio reports on the air.. |

have anyone here heard of highdrive. this means that the amp will take 15-20 watt deadkey. if you dont drive them proper then you will only get about 1/2 of its performance.howerver a low drive amp only handles around 4-5 watts input. this info was given to me from a cb shop with 30+ years in business |

im sure everybody has heard of high drive amps BUT just the same as a low drive amp they usually sound best with a about half of that 15-20 watt deadkey you mention im no tech but of all the amps ive had sure sounded a lot better drivin with about 5 watts max plus swing that included my texas star 350hd and 500hd with both of them if you were to put 15 watt carrier you would just about max it out there just with a deadkey and they dont sound as clean i usually have my radios set about 2 1/2 watts dk works best for me so just cause it says it will take 15-20 doesnt mean its gonna sound good or last very long |

Dale the only one ive even seen was a 250 high drive which took 4 watts MAX as for less output if you fine one that realy takes 20 watts your output would be less so would distortion and spalter bottom line if your radio puts out over 4 watta you would sound cleaner with one with some less output |

My customers ask "What does that mean printed on the front of this thing 'High Drive' ?"
I tell them it means basically two things:
1) "We knew you wanted to see it, so we printed it on the front panel, just so you would be more likely to buy it." Kinda like seeing "15% BRIGHTER WASH!" on the front of a box of laundry detergent. 15% brighter than WHAT ?
2) "Our replacement market is sagging. Please blow it up and come back for another one... Soon."
If you look inside one that says this, and look inside another that doesn't, there is no real engineering difference. This phrase is ALL marketing, almost no meaning.
Amplifiers that legitimately call for an external driver amplifier (8 or more transistors) are expensive enough, they don't have to have this printed on them. Nearly (I said 'nearly', not ALL) every amplifier you see with fewer than 8 transistors will not do well with a driver. You can make your meter read higher, but people will be wondering why you were louder before, even though your wattmeter was reading less that way.

Bruce what about an L-pad inline at the input a resistor to ground and one inseries in the shape of an L. |

Dale, either you misunderstood or you were misinformed. Maybe the shop you went to "meant" to say 15-20w of "peak" drive, not carrier. 15w of carrier into a 250, 350, or 400 "high drive" won't last very many minutes. |

hey guys my tech came over with his birdwatt meter . with the rfoutput all the way down its 8watts thats where i run it with my ts350hd. i guess thaT DOES SOUND A little better than 15-20 sorry my bad. my point is highdrives can be driven haRDER THAN low drives. the person were trying to helpout needs to know the output of his radio.to the guy with the question take your radio to your tech guy and have him tune it for that amp. |

Ok, for those of you Copper members other than Dale... I DON'T recommend putting 8w, 15w, or anything like that into any of the Texas Star amplifiers other than the 1200 and up.
Dale, I'm glad it works for you. |
