Hi John, Is there some reason you don't want the graphites? I have found them extremely rugged -- the Eimacs I had literally fell apart. I've been abusing mine (RF Parts Brand -- Taylors, I believe)

Also, try lengthening the coax between the amp & antenna. Hi-Sierra recommends 20-25 feet of coax for their screwdrivers. I have a HB copy of the HS, and indeed it makes a big difference in how it tu

What does the Metron use for Transistors? I'm running the ALS-500 with four 2SC2879s which is good for 5-600W out, band dependent. What does the Metron do? I was considering the Metron or Henry SS750

If it's like a TL-922, the same amount of 120V current pass through the fuses regardless of how it's strapped. It's just that on 240, the 120 phases are split. What's so hard to understand about that

Very nice!! Are the plates really purple-ish, or is that some kind of photo artifact? I've never played with 3-400s, but you have me motivated to get some images of my amp at "full smoke" now, too!!

Go figure -- as an Audiophile, I'm glad not all of us are "Audiofools". These go along with the "pure" cabling they sell. Incidentally, the kW+ auto-audio amp craze has made it pretty easy to install

That's true -- the vehicle charges when you are decelerating, as well as when the engine is running. Another heavy load like a high power amp would really put a dent in the power budget! I've always
