Not for me...a 4CW10,000A in the CERN lab nearly fried me in 1968. I am on my second solid-state amp in 18 years - first an IC-2KL/AT-500 for 10 years, and now an 8-year-old Yaesu Quadra. Both 100% trouble-free. Cheers for now, 73, Adam VA7OJ/AB4OJ Scanned for viruses by Blue Coat http://www.WinProxy.com/
