Thanks morzh. I did change R5&R6. R7 & R8 are within a few ohms of 80 & 150. I will change them to be sure and recheck the wiring. One question, I get 195v if I test from the center tap to the chassis. Does this seem correct to have that much difference in potential voltage btwn center tap and chassis ground?
