"Gerry" <[EMAIL PROTECTED]> made an utterence to the drakelist gang ---------------------------------------------------------------------- Of course, I always have to wonder about the accuracy of the wattmeter being used. If the meter previously indicated 150 to 200 watts and now only shows about a 100 then you might have a problem.

Is it that bad on all bands? If so, then it's probably not the tubes, as they'll lose output on the higher bands and keep it on lower, unless very bad. You might check your plate voltage, if one of the diodes in the voltage doubler's gone bad you could have low voltage and might still be able to load to 400ma, getting maybe 150w input, and 100 out. At normal voltages, 400ma at ~700v, you'd have 250-290w in, and should see 160-180+ out. How accurate are the peak measurements? If you're seeing 120w out on SB peaks on the plate meter, that's reasonable, it's slow, and you shouldn't see more than 1/3, maybe occasionally 1/2, of what you load up to on CW. 73, Al, W8UT New Bern, NC BoatAnchors appreciated here http://www.thecompendium.net/radio/ http://www.hammarlund.info ----- Original Message ----- From: "Matthew E.
