Revox A77 High Speed (7.5/15ips) mkIII 2 Track 1/4" Tape machine SM911

Revox A77 MK III High Speed (19/38) – Serviced, calibrated for SM911 For sale is a rare Revox A77 MK III factory High-Speed version (tape speeds 19 cm/s and 38 cm/s / 7.5 ips and 15 ips). The unit comes from a well-maintained, smoke-free environment. Key details regarding the service history (complete documentation/receipts available): The machine was fully overhauled and sonically optimized by a specialized workshop in April 2010. Since then, it has only been used for a single project (Recording & Stem-Mixing) and was subsequently stored in a dry and secure environment. • Full overhaul & sonic optimization: Technical Highlights of the Service & Optimization: All circuit boards were washed in a special liquid, all electrolytic capacitors were replaced with new, long-life industrial-grade components rated up to 105°, all RCA sockets were replaced with hard-gold-plated RCA sockets, all trimmers were replaced with high-quality Piher trimmers, all mechanical bearings have been replaced, including four ball bearings for the winding motors, a new ball bearing for the audio motor and a ball bearing for the left-hand idler pulley, the chassis components have been cleaned and the audio heads professionally demagnetised, and final computer-assisted calibration and adjustment have been carried out strictly in accordance with the service manual. High-End Power Supply: Custom ultra-low-noise stabilized power supply, featuring 40 times lower internal noise than standard voltage regulators, Premium Components: Upgraded with ultra-fast Avalanche sintered glass rectifier diodes, laser-trimmed spindle trimmers, and long-life Panasonic FC / Elna SILMIC II capacitors with ultra-low ESR, Signal Path Tuning: Optimized via ultra-low-noise transistors, non-magnetic Vishay-Dale metal film resistors, and upgraded signal cabling, Mechanical Upgrade: Left tape guide converted to a high-quality, ball-bearing roller for smoother and more reliable tape travel. • New capstan motor (Papst) Professionally calibrated/aligned for studio tape RMG / Recording The Masters SM911 (now RMT). Current condition (as of late October 2026): An extensive test run was performed prior to listing. The machine is fully operational and ready for use. The motors spool powerfully, the brakes engage cleanly, and the sound quality is outstanding. There are no audible degradations or storage-related issues since the service. The tape heads show minimal wear. The counter belt has been replaced and runs precisely and stably. Demo video instead of an on-site test: To allow you to evaluate the condition and get an impression of the input/tape comparison beforehand, I have created a recent YouTube video (filmed in UHD/60fps, audio recorded via Neumann KH120 monitors). I will gladly share the link upon request. Scope of delivery: • Revox A77 MK III High Speed • Power cord • 2x NAB adapters (standard version), one empty Revox NAB spool (26.5cm), one empty Revox Trident spool (26.5cm), one RMG 1/4" SM911 tape on a 26.5cm plastic Trident spool (762m), and one RMG 1/4" SM911 tape on an 18cm plastic Trident spool (366m) — both recorded for approx. 10 minutes • Complete documentation / service invoices from 2010 (Note: A dust cover is not included) Note: The displayed shipping fees of 50 Euro for Germany and 100 Euro for the EU are strictly system placeholders. I do not offer standard shipping myself, but transport can be arranged via third-party services or a specialized workshop at the buyer's expense and risk. Pick up (NO standard delivery/shipping): The following options are available: • Pick up from my place (preferred): A thorough test run over a cup of tea or coffee, with a demonstration via the Neumann monitors. • Meet halfway: I can, by arrangement, drive a certain distance to meet a serious buyer. • Courier service may be available for shipments to other EU countries – costs and risk to be borne by the buyer Note on transport and shipping: As a private individual, I do not have access to professional or secure packaging materials suitable for the heavy weight and delicate nature of this tape machine. To avoid damage, I therefore rule out standard postage. However, should a personal pick up or meeting not be possible, shipping may be arranged via a third-party provider. One possible option would be to arrange this through the specialist workshop that overhauled the Revox at the time. Such dispatch via a professional service provider shall be carried out exclusively on the buyer’s behalf, at their expense and at their risk. Since this is a private sale, the item is sold as-is, excluding any warranty, guarantee, or returns.
