"WF2U" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Let's see: L-4B original rated input is 2000W. at 50% typical efficiency, the output is 1000W. So, at 1500W output you're going to gain 10xlog 1500/1000=1.7 dB. Considering 1 S-point equals 6 dB, you're going to gain less than 1/3 of one S-point on the receiving end. You figure it out whether it's worth the expense and the reduced life of the pair of 3-500Z's...
