Default only .....

from the picture i ve seen .......

this will not stand full power ...... if you push it to the limit is simply gona blow......

laying all these transistors on a heat sink and using just a piece of wire to supply them will have a serious drop of voltage from side to side ...... i f you supply them in the midle then you will have drop in the voltage on the sides ...... if you supply them with more than one cable will solve the voltage drop problem but to my opinion will also create ocilation ......

different voltage in every trs will create the thing that actually some transistors will not help others or not share load ecually..... curent resistor also will not help in this level of diference


let us now how it works i am curious
