R241-JFET Q29 connection wire passes through C204 and passes through the PCB at the bottom of C205. If we are looking for -5.XV voltage, I suspect there is a strong suspicion here. That's why I suggest trying to remove C204 and C205.If there is no change, put it back as it was. |

Вut why don't you want to blow? I'm not asking to make a film about this, although it will be very interesting if the tension changes. |

Do you mean any tiny plastic hose? |
