hi I have seen here in other posts that there is talk of DOGC-H amplifiers by Dr. Borivoje Jagodic and I have printed the pcb but, if someone can help me x the psu or to the encumbrances of how many goes it must be a transformer power or in dual mono? I also read about studio SE. but I can not find the scheme x make the pcb and other info .. can you help me? thank you
