i have a punch 200s and when i got it it had some distortion in the left channel ( i can take pic later). i found one of the output fets (Q119/irf9540) out of tollerance. red probe to drain black to source my meter reads 792 ohms. any other time it's closer to 500 ohms. so i replaced it and checked the drivers but the distortiion is still there. any suggestions?
