Hi all, while trying to adjust DC offset on my Yamaha CR 840 the probe slipped and followed by a small flame that took out a resistor in the power supply section. This resistor is located in between a big white TRW 390R 5W resistor and the two 4.7 uf, 50V electrolyte capacitors. I looked at the service manual from online source hoping it is listed on the manual, however, I can only narrowed it down to the 800's resistors section of the schematic but couldn't tell which one it is to determine the value and type of the said resistor. It is a small resistor about a 1/4 inch in size. All this took was about a second or two before I turned the receiver off and I have not turned it back on since then. Is there anything else that might have damaged during this mishap? Thank you in advance for anyone's inputs and helps to identify it.
