It is a very, very rugged, heavy duty amplifier, with an extremely rugged power supply, with a huge power transformer, choke input filter, and oil filled filter caps. At over 150 pounds this amplifier is "built like a tank". - Of course all of this is in a very nice floor console, with the power supply in the bottom portion, and the RF portion in the top. - This one works like it should. With full power out of the exciter, it produces 1650 watts into a dummy load. - Cosmetically it is very close to perfect. I can not find a scratch or defect on it. - Buy it with manual for $1200. - Since it is 150 lbs, it is obviously pick up only, near Ocala, FL. - Thanks. 73, Ken Simpson, W8EK 352-732-8400 .

It will affix to concrete, cinder blocks or 16 in center studs. It includes 2 sandwich bars and a 10 ft copper grounding strap. It is ideal for mounting Polyphaser lightning arresters, and tying all of your grounds together. To say that this is very heavy duty is putting it mildly! - Apparently these list for about $900. I have seen them sold new for anyplace from $900 to $650. That seems much too high. - This one looks close to new, and certainly functions as new. If you are looking for something like this, this is an opportunity to get a steal. I will sell it for half of the lowest price I have seen, which makes it $325, plus shipping from Florida. - Thanks. 73, Ken Simpson, W8EK Voice Phone (352) 732-8400 .
