2500리시버와 2600리시버는 옛시절 가정용도 이상으로 사용하게끔 발매된 제품입니다. 즉.. 업소나 프로용으로도 사용할수있게 출고됐던 모델이며 두모델 모두 뒷부분에 팬이 장착되어 있습니다. 2500과 2600의 차이는 출력입니다. 무려 50w의 출력이 차이는 나지만 내부 설계는 거의 흡사하게 제작되어 있습니다. 2600리시버는 체널당300w 의 출력을 지원하며 2500리시버는 체널당 250w 의 출력을 지원합니다. 두제품모두 켄TR 16 구로서 구동력이나 FM수신률 음색이 강하며 파워풀한 소리와 함께 시원시원 한 음색으로 청감하실수 있습니다. 그리고 2600 리시버의 프리엠프부는 마란츠 리시버 프리엠프 아웃단중 최고의 스팩으로 제작되어 있습니다. 그만큼 프리엠프로 활용하셔도 훌륭한 소리 들으실수 있겠네요. 허나 두제품모두 오래된 제품에 약간의 고장만 나도 상당한 비용과 시간이 들어가기에 조목조목 잘살펴보신후 구입하시는걸 추천드립니다. 두제품 스팩 모두 복사해놓을테니 참고하세요^^ Marantz Model 2600 Receiver General Rarity X-Rare Retail Price 1600 Designed in USA Manufactured In Japan First Year 1978 Last Year 1980 Wood Case WC-124 Silver Face Yes, extruded Channels Two Tube Design One (Scope) IC Count 11 FET Count 12 Transistor Count 123 Diode Count 100 Speaker Connections Two sets Chassis Ground Binding Post AC Switch Yes Fusing Rear deck Switched AC Outlets One (US Model Only) Unswitched AC Outlets One (US Model only) Power Source Details Dual Toroidal Power Consumption 115 W (idle);
