I have an AL811H am that has no output. When driving the amp with 50
watts, the output on the watt meter shows a little less than 50 watts. The
weird thing is that according to the ammeter, everything looks like it is
loading just fine. I get about 75ma grid current, and the dip in the plate
current is about 450ma with 50 watts drive. Everything on the amp looks
fine, but no output.
So.eone said it might be the 2, .001, 7.5kv caps. I ordered some and
replaced them, but still no output from the amp. Any ideas??
Thanks and 73
