Bill, That is good to know. The 140 Watts I quoted was taken from the R-390A FAQ at http://www.r-390a.net/faq-overview.htm . It looks like we need to correct it. Does your 100 W measurement include the bfo and calibrator being on? From what I knew, I felt the actual was less than the stated 140 W. Also, is that with tube rectifiers?
