Hal, Richard didn't say he wanted a ton of headroom, he said he wanted to "put out a really big signal when the need arises." And I think his Alpha probably pretty much loafs at the legal limit. 73,

The question was specifically about the HLA-150V, not any of their other amps. According to the RM Italy website, the HLA-150V has 6 low-pass filters, manually or automatically selected. A glance at

This seems to be a very common occurrence in later Amperex tubes. The tube is at fault, not the amp- replace the tube and you'll likely get good service from the amp. 73, Scott, N9AA ________________

OK, time for more info. After removing all of the tubes, meter readings are OK. Putting one (I assume good) tube back in the amp causes the strangeness to begin again. Any ideas? 73, Scott, N9AA ____

OK, I have taken all the tubes out of the AL-572 and put only 1 in at a time and turned the amp on each time, with the same results: a slight negative pulling of the grid current meter and then a slo

Maybe you should see what they do as a monoband on 11 meters. There's a lot more money in that and fewer people would question your work. Just a thought... 73, Scott, N9AA ___________________________
