hi apexaudio
greetings completed amplifier sucessfully great detailed sound
very powerful amplifier very sweet sound .THANKS for your schematic and
COOPERATION all the way otherwise this great amplifier would not have
been possible no heating problems today i will make dc protector
1 can i put 4 pairs more on same heat sink would it result in more power in 4
ohms do not want to run amp in 2 ohms
2 mj 15024 15025 available but i suspect fake transistors

THANKS once again apex audio one more milestone crossed

Yes, you can connect primary in parallel, and secundary in series. Conection beatwin secundary will be CT, and you have 2x84vac at the end of secundary.
