In most cases 2 x 2879 setups are happy to chug along at 225-250 watts for years without difficulty. In addition to run an amplifier at maximum produces a large amount of heat, requires higher input and maximum allowable voltage, and the end result is that your amplifier will not last as long. I’ve seen the Texas Star 350HDV (2 x2879) advertised as having maximum output of 350 watts PEP, but truthfully most operators will never see the maximum advertised output out of their amplifier.

A proper install with the necessary rated power wire is essential in getting the full potential out of any amplifier. A number of different factors will effect the output of your amplifier and so it could be expected that in different setups people may see higher or lower numbers than mentioned here. Most people on average will run these on AM with PEP input of 20 watts average 13.8 volts and you’ll see around 225-260 watts PEP output. Now most vehicles and power supplies are set up to run higher than 12 volts and with that extra voltage these transistors see higher output, so even though the transistors are rated at 100 watts each at 12.7 volts when you run them at 13.8 volts or 14 volts you’ll see higher output. The Texas Star 350DX uses two Toshiba 2879’s transistors which are rated for 100 watts PEP each at 12.7 Volts Now I’ve read some discussions online that technically the Texas Star amplifiers are not a true “AB” biased amplifiers but for the purposes of this review we will call them a AB biased amplifier in comparison to how other “Export” amplifier are rated for biasing. Texas Star Amplifiers are claimed to be AB biased which would make them a good choice for SSB operation. And that’s one of the reasons the Texas Star line of amplifiers is a favorite of people who run SSB. On SSB if you run a overmodulated or distorted station often people in DX land will have trouble clarifying you in, or will overlook making contact with you because of the way you sound.
Most CBer’s on AM don’t really care if their signal sounds distorted or scratchy, they just want to be loud. They will talk about how “clean” their amplified signal is when it comes out of the amplifier. Now right away I’ll tell you that if you are looking for something that delivers a lot of bang with low amperage pull than this is not the amplifier for you.Ī somewhat more rare amplifier discussion will be heard between operators who mainly use SSB. Most radio enthusiasts are looking to run the largest amp possible with the least amount of amperage draw. When most people discuss amplifiers the main topics that come up are output power and amperage draw. Texas Star DX 350 CB Radio Amplifier Review
