A friend of mine built this. I dont know very much about it except it has 3x 3-500z and does around 4kw. Enjoy tell me what you think. and it also has an SSB biasing circuit in it. he doesnt run it on am because he believes in being polite to his tubes. oh yeah They arent Actual eimacs their like knock off 500z's but they work good. he told me a story about him driving down the road. when all of a sudden his buddy calls him on the cell and says "dude your antenna is on fire." He ran a Leesville alt with it too. hasnt powered it up in about 10 years. no use for it and no vehicle to put it in. i keep trying to convince him. and YES it is in a old heathkit box but there isnt anything from the heathkit in there he rebuilt the entire thing.
