[#5] etsang3 修理 Marantz PM5 哩部機其實比一間頗出名公司HiFi修理公司整過,機主話唔知點解,呇aCUT鱄笏lass A 掣弁,CUT鱄茩悸OLED VU 錶CUT弁, 我睇黎都要化D時間還原"真身",嗚~部機靚樣又幾真才實料,不過堶扈u係要大執"咿R",我工作仲係咁忙,要整多兩個星期都似勒, 希望機主了解啦。 "大清洗" ![]() |

[#8] etsang3 修理 Marantz PM5 * 換入音色不匹配管 * 唔換入正式正確數值電阻 * 一邊聲道換入代用輸出管,又唔通知機主及問一問要否全部換哂,達至音色最平衡 ![]() |

[#15] etsang3 修理 Marantz PM5 etsang3 兄, heard that after replace the transistor, there should be a turning kots for adjust bias. Could kindly show us this step and what value should we follow?? THX |

[#16] etsang3 修理 Marantz PM5 wo hing, you means this PM5 ? There is no VR pot on the board to adjust the BIAS wor (?) It is using fixed resistors for BIAS. (I will post the whole circuit after I clean my drawing). And a switch called CLASS A seems to make the BIAS a little bit higher. Based on only a heat pipe heatsink, I don't think PM5 can be real CLASS A amp. Also the power supply section is not enough to support CLASS A. |

[#17] etsang3 修理 Marantz PM5 Small Vin, how is your amp ah ? Do you try to find a better one to replace it ? Is the Tuner receiving OK at your location ? Good Health to you too. |

[#18] etsang3 修理 Marantz PM5 etsang3 hing, not just PM5 but typical power amp circuit. Back to PM5 type, "fixed resistor" (you did mention the 33ohm). how should user measure after replace the power transistor? Also, the high power rating resistor (big size) alway cause problem, what the use of this resistor uausally? ** Sorry for too many questions ** |
