(E03_) :ifrelw RadioFans.CN KA-5050R CONTENTS Handle the power MOS-FETs carefully. They are easily destroyed by static electricity. When soldering, use a high-insulation soldering iron. When soldering, solder the gate (G) first. NOTES ACCESSORIES When replacin! the power MOS-FET, there are differences according to the ranks, so please replace Pch (or Nch) as a pair of identical rank. The parts stock for parts of the same rank as Pch (or Nch) come in packs of pairs. When ordering a quantity of 1, one pack (containing 2) will be delivered in one bag. Please order as 25K1529LBP4, 2SJ200LBP4. There is no need to adjust the ranks of Pch and Nch, and there is no need to adjust the ranks of the left channel and right channel either. Since the KA-5050R is a FET amp, even with no signal, nearly as much heat is generated as for maximu m output. When piling sets on top of each other, put this amp at the top. Placing any other unit on top of this amp interferes with the heat release and can cause harm, so do not do this.
