While it's true that you probably can't overdrive the L-7 with 100W, you probably CAN drive it past the legal limit, especially on the lower bands. The power supply and tubes have the dynamic capability, even though it wouldn't support key-down CW at those levels.
The ALC from the L-7 is negative going, and is adjustable from the front panel. So you're better off using the ALC and setting it for the legal limit or less with a monitor scope. 3-500Z's aren't cheap any more, and the difference between 1200 and 1500W is not discernible from the other end.

"Kevin Nathan" <[EMAIL PROTECTED]> made an utterence to the drakelist gang ---------------------------------------------------------------------- Hi All,
I will be driving my L-7, when I get it, with a Kenwood TS-480SAT, maximum of 100 watts. I have been advised by a couple of people that with this level of drive, I really don't need to worry about connecting the ALC line. I would like to know if there is agreement with this opinion or not among owners on this list. If ALC is recommended, the manual for my 480 says the ALC input from the amp is -7V. Would this be compatible with the ALC output of the L-7?
Thanks for your thoughts on both of these questions and very 73.
Kevin :)
