I am only getting 0.152v ac on the output when engaged. I believe the transformer is oriented correctly and solder joints appear clean. I am getting 0.14v ac @ U2 pin 4 and U2 has power. I hear the relay click when taking out of bypass. I also tried cleaning the tube pins. Please advise, Thank you
+15.6 v
