A&R Cambridge SA-200

A&R Cambridge SA-200
Power amplifier 2 x 100W/ch
Made in England
A&R Cambridge adalah produk lama , A&R Cambridge dulu menjadi satu yang pada akhirnya berpisah dg produk Arcam dan Cambridge
Sebenarnya type ini adalah gabungan dari Pre dan power tp pre nya tdk ada
Power ini cukup bagus, dg pemakaian travo toroid yg cukup besar, capasitor power supplay 4 pcs per chanelnya,PCB terpisah mono-mono dg komponen yg bagus .
Power dipersenjatai dg 8 pcs transistor RCA model jengkol, 4 pcs /chanel sudah cukup bertenaga
Anda bisa lihat daleman komponen power AR Cambridge ini pada foto-foto yg saya tampilkan
Semua masih original
Harga : Sold to Mr. A.S - Bdg
Dengan harga yg masih sangat layak dan sepadan untuk kualitas power amplifier ini.

Description

　
Stereo power amplifier which can change a pure Class-A and AB class.

The pure Class-A operation is adopted and the output at the time of a pure Class-A serves as 30 W/ch. Moreover, it can be used also as AB class operation 120 W/ch by switchpoint change.

The material is selected carefully and adopted while introducing an advanced Low-TIM design.
There is sufficient margin for a collector loss in a power transistor, and the high speed high fT transistor which was moreover excellent in the high region property is adopted. The cut-off frequency of quantity is 90MHz, and this transistor suppressed switching distortion which was not able to avoid AB class, and, moreover, has also realized flattening of a high region phase response.
Moreover, it has a whole page perfect push pull DC amplifier stream composition in circuitry, a modification of a nakedness property is aimed at, and the amount of NF is reduced. TIM distortion is decreased without spoiling a static characteristics. Furthermore, DC drift which poses a problem with DC amplifier also controls a property by the part and DC servo circuitry which were arranged ideally, and the height of a robustness is also thoroughgoing.

In the exothermic by pure Class-A operation, a heat-pipe scheme is adopted and heat is radiated. Heat is drawn outside a circuitry by a heat pipe, and heat is radiated by the radiator.

The 22,000-micro F super audio capacitor driven in from double-sideds of a property and an audition is used for a capacitor, and it is thinking as important the rich musicality which does not appear in a data.
Moreover, the transformer was filled up with the special resin and it has succeeded in a heat-resistant measure and miniaturization.

The highly precise large-sized power meter of a logarithmic comression indication is arranged, and the Direct reading of the power at the time of an 8-ohm load intensity can be carried out. And the speaker selector in which a class A switchpoint, a power switch, two speaker changes, and a simultaneous play are possible was equipped in the traditional sub panel, and it is finished in the simple design.

* The photograph has equipped the option mahogany cabinet.

M-90 Pioneer Reference Power Amplifier
Dengan desain yang mewah,sangat jarang kita temui di pasaran
Yang membedakan adalah dipakainya bahan tembaga murni untuk sebagian casing bagian dalam dan tutup bawah dari casing preamplifier maupun power amplifiernya.Dan untuk jaman sekarang sdh tdk ada lagi pemakaian tembaga murni untuk casing sebuah audio,karena memang produksi jadi lebih mahal.
