마란츠 최고의 명기이자 미국의 마란츠사를 도산하게 만들었던 제품인 10B 진공관 튜너 입니다.

미국에서의 마지막 메이커로 보셔도 될정도로 과도한 내부투자로 인하여 회사가 도산되어 일본으로 넘겨

졌으며 그만큼 현재에는 과거의 저튜너의 명성으로 마지막 메인튜너로 장착하는 손꼽히는 제품입니다.

그만큼 소리와 내부만듬세 완성도가 완벽함을 말해주며 국내에서 극상품이라고 치부할만한 제품이 극히

드믈정도로 내부와 앞면의 패널교체 여부 오버홀이 안된 상태가 거의 드믄제품중 한제품 입니다. 현제품

은 내부 오버홀과 조정이 안된상태 이지만. 작동은 퍼펙트하며 내부의 12AU7과 12AX7 8알 모두 텔레풍켄

각인관으로 채용하여 기기의 퀄리티를 높여 놓았습니다. 또한 앞면의 패널교체가 많은 제품이지만. 현제품은

패널역시 상처없이 클린한 오리지널 패널이며 오리지널 케이스와 내부상태 역시 엄청나게 깨끗함을 유지

하고 있습니다. 스테레오 분리도 우수하며 음질은 수준급입니다. 전원115v 사용하며

How the Model 10B Differs from the Model 10

The Model 10b uses gapped pot cores cores for the IF stage inductors. Marantz found that the the toroid cores used in the model 10 were becoming magnetized on the production line due to the use of Weller soldering equipment (these use a temperature-sensitive magnetic tip to control the applied heat energy.)

When the magnitization occurred, the tuners could not be aligned, and this required a costly re-work of the model 10 tuner prior to shipment, hencce the change for the 10B production run.

The dial mechanism was also redesigned from the model 10 for the 10B production run.

In the 10B, the IF stages were aligned in an oven. Marantz engineering knew that the chassis would run at a certain temperature, so they designed a setup which would keep the IF strip at the correct temperature for alignment, thus ensuring that once the tuner reached its normal operating temperature, it would be completely "peaked".
