The Technics 1520 has long been regarded as one of the prized tape decks. Impeccable consideration to the points only the most meticulous of audiophiles would understand. Below is a description of this one of a kind rebuild.
Reel motors totally disassembled. Plastic tridents, which are a subject to break easily, are replaced with metal tridents made from non-magnetic aluminum bronze. Bronze bearings inside motors cleaned, filled with lubricant.
Brake drums removed from the shaft, old paint stripped. Repainted with glossy hard scratch resistant high temp paint. Quality of this paint is crucial for proper brakes. Table painted to base machine color. Shaft assembly with brake drums and tridents balanced. Motors assembled.
Capstan motor disassembled, cleaned. Aluminum cup removed and replaced with another one made from nonmagnetic aluminum bronze. Precisely machined and polished.
Bearings replaced with original NOS NSK(made in Japan) bearings. Incredibly silent.
Capstan assembled, installed .
Old aluminum background sheets removed. Scanned with precision scanner. New graphic file suitable for laser engraving created. Replaced with non magnetic copper sheets, laser engraved, painted to base machine color. Graphics 24K gold plated.
Black paint from arrows removed, arrows painted with fluorescent paint (0xBD09F5 color).
Head block disassembled. Plate stripped, cleaned, painted to base machine color. New metal letterings and some metal accents applied. Heads had incredibly low usage, relapped & polished under water. Resoldered, realigned. Head block reassembled. 4t-2t switch disassembled, cleaned, reassembled.
Large 128x22px screen with bright YELLOW pixels. Powered by SSD1305 and Teensy4.0 (600MHz) controllers. Auto scaling with speed switch on left panel. With memory on power off. Prewired for future installation of WiFi remote control and programming block. Screen installed on totally reengineered counter and cue plate , 3D printed on Formlabs3+ printer from high temp resin, powder coated to base machine color.

All back connectors replaced with gold plated. AC cord connector added.
All visible metal parts are hand made from non magnetic aluminum bronze polished.
A FEW words about METAL.
Aluminum bronze C62400 composition contains up to 11.5% of aluminum, which creates protective oxide film almost immediately after polishing. Will remain shiny for a long time. Color is slightly darker than gold by design.
Needless to say all letterings are made from the same metal, 0.75mm raised.
Splicing block fully functional with spring loaded levers.
Cuts for blades are made for 22.5 and 45 deg for right and left handed peoples. Insert for lower panel levers also CNC machined from C62400, polished.
Also, needless to say, but, the deck is fully recapped and readjusted.
All old Philips bolts were replaced with new HEX just to make future maintenance easy.
Side panels are made from African Rosewood AKA Palisander (while machining smells like roses it's funny). Treated with special blend oil, polished. Each flange on side panels has engraving "Technics RS-1520".
