PS Audio PerfectWave BHK Signature 250 power amplifier, perfect, original packaging and manual, black, purchased new in September 2022, regular Italian import.This stereo power amplifier occupies a prominent position in contemporary high fidelity. Designed by legendary engineer Bascom H. King (hence the BHK acronym).Tube Input Stage: Uses a pair of selected triodes operating in Class A. MOSFET Output Stage: The signal is then delivered to a high-current MOSFET power stage. King chose MOSFETs because, unlike bipolar transistors, they have a duty cycle more similar to that of tubes, ensuring power and control without sacrificing musicality.Main Technical FeaturesPower: Delivers 250 watts per channel into 8 ohms and doubles to 500 watts into 4 ohms. It is stable even into difficult 2-ohm loads.Through-Hole Construction: Unlike most modern devices that use surface-mount (SMD) components, the BHK 250 is constructed entirely with through-hole components and hand-soldered joints, a choice dictated solely by the pursuit of maximum sonic fidelity.Separate Power Supply: It features independent transformers and regulation circuits for the input and output stages, minimizing interference.Inputs: It features both balanced (XLR) and unbalanced (RCA) inputs.Outputs: Two pairs of gold-plated copper binding posts (CNC-machined by PS Audio), ideal for bi-wiring.Weight: 37.8 kgDimensions (W x H x D): 43.4 cm x 22.1 cm x 35.6 cm
PS Audio PerfectWave BHK Signature 250 Endverstärker, Perfect, Originalverpackung und Manual, schwarz, neu gekauft im September 2022, regulärer italienischer Import.Dieser Stereo-Endverstärker nimmt eine herausragende Stellung in der zeitgenössischen High-Fidelity ein. Entworfen vom legendären Ingenieur Bascom H. King (daher das Akronym BHK).Röhreneingangsstufe: Verwendet ein Paar ausgewählter Trioden, die in der Klasse A arbeiten. MOSFET-Ausgangsstufe: Das Signal wird dann an eine Hochstrom-MOSFET-Leistungsstufe geliefert. King entschied sich für MOSFETs, weil sie im Gegensatz zu bipolaren Transistoren einen Duty Cycle haben, der eher dem von Röhren ähnelt und Leistung und Steuerung gewährleistet, ohne die Musikalität zu opfern.Haupttechnische MerkmaleLeistung: Liefert 250 Watt pro Kanal in 8 Ohm und verdoppelt sich auf 500 Watt in 4 Ohm. Sie ist selbst bei schwierigen 2-Ohm-Lasten stabil.Durchbohrungskonstruktion: Im Gegensatz zu den meisten modernen Geräten, die Oberflächenmontage (SMD) verwenden, besteht der BHK 250 vollständig aus Durchbohrungskomponenten und handgelöteten Verbindungen – eine Entscheidung, die ausschließlich vom Streben nach maximaler Klangqualität bestimmt wird.Separates Netzteil: Es verfügt über unabhängige Transformatoren und Regelkreise für Ein- und Ausgangsstufen, wodurch Störungen minimiert werden.Eingänge: Er verfügt über sowohl symmetrische (XLR) als auch unsymmetrische (RCA) Eingänge.Ausgänge: Zwei Paare vergoldeter Kupferbindestifte (CNC-gefräst von PS Audio), ideal für das Bi-Wirbeln.Gewicht: 37,8 kgAbmessungen (B x H x D): 43,4 cm x 22,1 cm x 35,6 cm
PS Audio PerfectWave BHK Signature 250 amplificador de potencia, perfecto, embalaje original y manual, negro, comprado nuevo en septiembre de 2022, importación italiana regular.Este amplificador de potencia estéreo ocupa una posición destacada en la alta fidelidad contemporánea. Diseñado por el legendario ingeniero Bascom H. King (de ahí el acrónimo BHK).Etapa de entrada de válvulas: Utiliza un par de triodos seleccionados que operan en Clase A. Etapa de salida MOSFET: La señal se entrega entonces a una etapa de potencia MOSFET de alta corriente. King eligió los MOSFET porque, a diferencia de los transistores bipolares, tienen un ciclo de trabajo más similar al de los bulbos, asegurando potencia y control sin sacrificar la musicalidad.Principales característicastécnicas de potencia: Entrega 250 vatios por canal en 8 ohmios y se duplica a 500 vatios en 4 ohmios. Es estable incluso en cargas difíciles de 2 ohmios.Construcción por orificio atravesante: A diferencia de la mayoría de dispositivos modernos que utilizan componentes de montaje superficial (SMD), el BHK 250 está construido íntegramente con componentes de orificio atravesante y uniones soldadas a mano, una elección dictada únicamente por la búsqueda de la máxima fidelidad sonora.Fuente de alimentación independiente: Cuenta con transformadores independientes y circuitos de regulación para las etapas de entrada y salida, minimizando la interferencia.Entradas: Dispone tanto de entradas balanceadas (XLR) como desequilibradas (RCA).Salidas: Dos pares de postes de encuadernación de cobre chapados en oro (mecanizados por CNC por PS Audio), ideales para doble cableado.Peso: 37,8 kgDimensiones (Ancho x Alto x Larga): 43,4 cm x 22,1 cm x 35,6 cm
PS Audio PerfectWave BHK Signature 250 güç amplifikatör, mükemmel, orijinal ambalaj ve manuel renk, siyah, Eylül 2022'de yeni satın alındı, normal İtalyan ithalatı.Bu stereo güç amplifikatörü, çağdaş yüksek kalitede önemli bir konuma sahiptir. Efsanevi mühendis Bascom H. King tarafından tasarlandı (bu yüzden BHK kısaltması).Tüp Giriş Aşaması: Class A'da çalışan seçilmiş iki triod kullanır. MOSFET Çıkış Aşaması: Sinyal daha sonra yüksek akımlı bir MOSFET güç aşamasına iletilir. King, MOSFET'leri seçti çünkü bipolar transistörlerin aksine, tüplere daha çok benzeyen bir görev döngüsü var; bu da güç ve kontrolü müzikalden ödün vermeden sağlıyor.Ana Teknik ÖzelliklerGüç: Kanal başına 250 watt 8 ohm'a iletir, 4 ohm'a ikiye çıkar 500 watt'a çıkar. Zor 2 ohm yüklerde bile stabildir.Delikten Yapı: Yüzey montajlı (SMD) bileşenler kullanan çoğu modern cihazın aksine, BHK 250 tamamen delikten geçen parçalar ve elle lehimlenen eklemlerle üretilmiştir; bu tercih yalnızca maksimum ses hassasiyeti için belirlenir.Ayrı Güç Kaynağı: Giriş ve çıkış aşamaları için bağımsız transformatörler ve düzenleme devreleri içerir, bu da paraziti en aza indirir.Girişler: Hem dengeli (XLR) hem de dengesiz (RCA) girişlere sahiptir.Çıkışlar: İki çift altın kaplamalı bakır bağlantı (PS Audio tarafından CNC ile işlenmiş), çift kablolama için idealdir.Ağırlık: 37,8 kgBoyutlar (K x H x D): 43,4 cm x 22,1 cm x 35,6 cm
