Technics - RS-1506US Reel to reel deck 26 cm

Technics RS-1506US – Isolated Loop – Fully Revised – 4-Track
One of the most iconic legends of analog audio.
I am offering for sale this magnificent Technics RS-1506US (4-track version), produced during the golden age of Japanese hi-fi (circa 1977-1980). This model is famous for its unique "Isolated Loop" tape transport system with quartz-controlled direct drive, providing exceptional rotational stability.

Condition and Revision:
The unit has undergone a full professional overhaul. It is aesthetically in superb condition (see high-resolution photos) and fully functional for playback as well as recording.
Important technical note (Brakes):
For complete transparency, I should note that when stopping after a fast rewind/fast forward (advance or reverse), the braking is slightly lacking bite, creating a small "slack" in the tape before it comes to rest. This is a minor issue that does not affect sound quality or daily use, but a simple tension adjustment can be performed by the future owner for absolute perfection.
Prestige accessories included:
NAB adapters: A pair of high-quality adapters (Revox-style) for 26.5 cm reels.
Metal Reels: Two legendary 10.5" (26.5 cm) reels included: one Maxell and one Akai.
Tapes: The reels contain magnetic tape. Note: The recordings currently on these tapes were not made on this Technics, so listening quality may vary depending on the original alignment. However, recording tests conducted on this machine after the revision were excellent.
