| [#812] 昔日重料制作 不知重料定義，自己覺得依部後級好堅，應該出過幾期，平衡版本自己未用過，不敢下評語，但初期版本真係好好聲 electrocompaniet Ampliwire 100  |

| [#810] 昔日重料制作 Class A, Integrated Amp : 在 2010 年，大部份 Class A 合併机只有 30 Watt Output. 而 PI Greco , 一台 PI-40A 竟是 Class A, 40 Watt 輸出， 全平衡 Mono 設計， 每邊用 12 隻 Power 管， 兩支共 138,000 uF 電解電容，重料制作。 當年定價頗高， 在香港欠缺宣傳， 銷售數量不多， 短短十年 ，此货號已沒有進貨。 最後修改時間: 2022-11-10 15:43:01 |

| [#807] 昔日重料制作 #805 冇位加散熱器，下面一字係我多加一塊epoxy 板隔熱，圈住是black module, 呢部MZ1好熱，所以好多black module 整瓜，加這塊epoxy 板可有效隔熱，到現在仍健在  最後修改時間: 2022-10-12 20:00:53 |

| [#806] 昔日重料制作 1980年MZ1推出，7700港元係好多錢，當時政府初級文員才一千多元 |

| [#802] 昔日重料制作 Black Module  |

2022-10-12 00:28 |
| [#801] 昔日重料制作 The black module(the zero feedback amp module) in MZ1 or MZ1a is very easy to be damaged due to heat dissipated by the heat sink. The heat sink is very hot due to its 60 watt class A operation. Not many MZ1 or MZ1a still function nowadays because the module is dead. I improved the structure in MZ1 heat problem by inserting a epoxy board between heat sink and black module as to isolate the heat radiated by the heat sink  最後修改時間: 2022-10-12 00:26:21 |

| [#800] 昔日重料制作 According to http://www.thevintageknob.org/pioneer-M-Z1.html Wow. U really have some special stuffs Some said that series have a good sounding phono stage too It seem quite special... M-Z1a 1 9 8 01 9 8 11 9 8 4 Completely unknown elsewhere, the Z1 series nevertheless sold extremely well in Japan - a staple of the well-heeled audiophile rigs of the times, alongwith the Exclusive P3 turntable. The Z1s were Pioneer's entry into 1980s super high-end of the non-NFB kind through the Super Linear Circuit for the voltage amplifying stage. The SLC works with two transistors : cancelling the non-linearity of the first with the second's non-linearity in reverse mode. Since there is no NFB loop(s), DC stability is achieved with a double-locked servo regulator. The output transistors are three pairs of LAPT devices (2SA1187 / 2SC2838) all working in Class A, naturally : the M-Z1 are hot boxes. Two transformers, select and non-magnetic parts, glass-encased caps with carbon-coating inside glass and special electrode foil, 140µ glass-epoxy boards, OFC wiring - and then some. At 320,000¥ apiece, this was for the non-compromising indeed, but for the well-heeled only as well. |
