The relay should then open. The power supply board seen from the solder side NOTE! lnput FETs 0103/0104 and O203/O2O4 are matched pairs, and should be.replaced with the same group. Each matched pair of transistors needs a spesific value of source resistors (written by hand on the pc board). After replacing the FETs, check for correct current. The voltage across R147 /R247 should be 2.2Y t 0.2 V. All measurements in the amplifier must be made with a probe having minimum 5 kohms.
