To tell you the honest truth, I went down to channel 6 one time. It was a few years back. I had acquired a 24 pill class c amplifier/power supply combo on a trade for an old Ford pickup I had parked over yonder in the yard. Of course I had to do a test run and see how it worked. I went down to 6 and keyed it down. I remembered my legs were shaking...lol Never ran that much power before. I said " We gonna key it up this time, and we ain't gonna key it again. World Wide 75 saying heeeeello" I un-keyed and heard everyone calling back for me. I turned the power supply off, turned to my friend and said done deal! and shook his hand. I have never been back. Still got the amp but sold the power supply to another friend that offered an amount I could not refuse. I think I'm gonna hang on to that amp still. Maybe I can find me another 220v bigass supply down the road to get her back up runnin'
