The maximum wasted power of compensating pipe T1 shown in diagram (a) is 5.6W. The radiator of compensating pipe T1 can be made by aluminium plate with 2mm thick and 100mm×100mm area. Need regulated voltage can be adjusted to 20V by 1kΩ regulation resistor which is connected at base of transistor T3. transformer winding number: n1=1600turns, 0.25mm copper lacquered wire n2=180turns, 0.7mm copper lacquered wire The maximum wasted power of compensating pipe T1a and T2b shown in diagram (b) can reach 14.5W. Each transistor radiator can be made by aluminium plate with 2mm thich and 120mm×120mm area. transformer winding number: n1=1190turns, 0.35mm copper lacquered wire n2=145turns, 0.8mm copper lacquered wire
