Can anyone tell me that why the MJ2955, 2N3055 never get warm but then I can use RV1 and RV2 to adjust and obtain 0.66V across R10 and zero DC at output. Thanks to Geoff recently helped me out to resolve the 180 degree wrong insertion of Tr4 by me. His kindness and expertise really encourage me not to give up my very first ever DIY of any kind.
