Countryboy... Maybe not screaming in caps at people trying to help would get you a bit better response from others.
I have to echo psycho's sentiment, though.
Red is not a hi power switch. It's called a power switch. It turns the friggin amplifier on and off.
You can go get a friggin instruction sheet off Texas Star's website.
There, as Psycho pointed out, an indicator on the front of the amplifier that will tell you what is what, but since you can't seem to figure out what a meter does, how to download a tech sheet, etc., I'll do the rundown for ya:
Red: Power On / Off for the TRANSMIT amplifier
White: Power On / Off for the RECEIVE amplifier
Orange: Hi / Low for AM AND SSB USE
yellow: SSB Delay.
Some "idiots" think that the yellow switch is another "power level". NOPE. The Texas Star amplifiers run such high gain (and in the days of Bilinear, Bilateral and Outcomm, they ran LOTS of gain in EACH stage in their multi-stage amps) that they saturate with normal SSB input levels (and your's is designed for 20 watts MAXIfrigginMUM!!!!). To keep the amplifiers from saturating, trashing the band and sounding like a CB amp, Texas Star switches in a pad on SSB (and as far as I know, they are the ONLY ones that do this) that lowers the stage gain, and incorporates a little feedback (and I'm not going to argue this point, go learn advanced AC if you want to) to lower IMD (what you CBers refer to as "bleedover", depending on the 'order').
You CAN use it as a power level, but that's stupid. Any "power level" switch in a CB amplifier is nothing more than a resistor switched in line (except in a couple hurricanes, some Silver Streaks (yeah, no bullshit, the early ones used a pair of input windings) and a couple other EARLY SS amplifiers) to drop the drive voltage to the stage... Which accomplishes what they wanted, but also increases the VSWR.
Buy an amp big enough for your needs. If it's too big, get an ATTENUATOR to go inline for TX. If it's too small, we call it a driver.
As to the gentleman asking what the toggle switch is for, some 'tech's' put a toggle switch in the same place (texas star uses the same chassis for the variables and non-variables.... The plastic front won't have the hold drilled, but the chassis usually do) that the variable goes to switch the SSB delay. NO AMPLIFIER THAT TEXAS STAR PRODUCED HAD A TOGGLE SWITCH THERE!!!! It's a hack, and conjecture as to what it is.
I'd be willing to bet it's a hack to allow another hack to have a "power level" switch out of the yellow "SSB" switch.
