What watt meter are you using ? Sounds like it may be squirrly.

The wattmeter pegs past 2kw and 4 572B tubes cannot put out that much power and also the plate current only reads about 400ma at 2400 vdc so there is no way the output is that high.  10 meters works ok also.  I will not use the amp on 15 until I find out what is going on.
