2k and up. I use copper pipe instead of fuses sometimes to keep it glowing.
I got 440 also, I do welding also though. |

I had a homeade mobile a friend of mine put together, straight eight pill, volted up, and tickled 3000 with it. I saw a guy with a 10,000 watt ac amp in a suburban. He didnt have it all grounded right at first, and his girfriend had a necklace around her neck and it touched a door when he was keying up, and it burnt a ring around her neck! |

Mobile 3k, base 5k. As you can tell I drive a suburban too. Have to have room either a van or suburban.
Legal limit of course now. |

many good ham sites on this topic. do an serch on the web youll find them.
im mauling (mual get it?)over a project rite now on converting a phantom 500 over to be either a single or dual ceramic amp. i just need the specs on the 3 transformers they use to see if thier big enuff to power two of them or not.
thier more to it than that, its a total rebuild but im tring to get the high voltage,ect figured out first before i start ripping it apart. |

Save yourself the trouble get a dentron 2500 or heathkit sb220. There is a heathkit on e-bay thats not put together to to much money for me but it uses one 3-500z. I can show you a 10 tube amp with 3-500z's. I looking into now adding a extra 3-500 to my heathkit I just now got the extra socket and another tube wish me luck. |

crafter,
ive got a sb220, would like one like the one on ebay but dont have that much cash for it right now.
ive also got two old 10 tube boat anchers i want to convert for several reasons.
one is the price of 6lq6's are to high $35-$50 per tube NOS. thats $350-$500. and thier to old and frail to warrant retubing with them. a pair of zg's run $279.
secondly EL 509's are a good fit, and are cheaper and more rugged/more powerfull than the 6lq6. and the mod is not very difficult. but it will still run around $200 to tube it after the mod and maybe another 40 for sockets if you have to use them. so now were at $240 dollars.
then 3rdly the way i plan on doing this ill have only 2 tubes to buy from then on,at a fraction of the cost of a new set of these sweep tubes and have better performance.
plus the fun and learning experiance of building it your self.
a part of the radio arts right.
i say this now anyway half way through the project i might agree...lol
later Crafter
p.s.
good luck on your project.
