REEL-TO-REEL TAPE ACCESSORIES — THE BUYER’S GUIDE
A good reel-to-reel tape recorder is only part of the analogue experience. The right accessories make the machine easier to use, safer for valuable tapes, and far more enjoyable to own.

Whether you use a Studer, Revox, Technics, Pioneer, Otari, Akai, Sony, TEAC, Tandberg or another open-reel machine, this guide covers the most useful accessories worth buying, what they do, and what to look for before spending your money.
1. EMPTY REELS
Empty reels are one of the first accessories most reel-to-reel owners buy.
Common sizes:
● 5-inch
● 7-inch
● 10-inch
● 10.5-inch / 26.5 cm NAB
For serious 15 ips listening, 10.5-inch reels are especially popular as they hold longer lengths of ¼-inch tape.
Plastic reels
Pros:
● Lightweight
● Affordable
● Easy to find
● Good for everyday use
Cons:
● Less rigid than metal
● Can warp over time
● Less premium appearance
Aluminium reels
Pros:
● Strong and rigid
● Better tape protection
● Premium look
● Ideal for master tape copies
When buying aluminium reels, ensure they are flat and balanced to avoid vibration or tape edge issues.
2. NAB HUB ADAPTERS
Large professional reels use NAB centres instead of smaller Cine-style hubs.
A NAB adapter connects the reel to the machine.
A good adapter should:
● Lock securely
● Run perfectly concentric
● Hold without wobble
● Be easy to fit/remove
● Avoid scratching reels
● Match the machine properly
High-quality aluminium and precision-machined versions are recommended, especially for Studer, Revox, Otari, and Technics RS-1500 series machines.
3. REEL CLAMPS
Some machines use clamps instead of NAB adapters.
Always use the correct system for your deck.
A loose reel can slip during fast wind, while over-tight clamping can damage the hub.
4. REEL SPACERS
Small but important accessories placed between reel and reel table.
They help:
● Improve alignment
● Match different reel manufacturers
● Prevent tape edge rubbing
Especially important for valuable master tapes.
5. LEADER TAPE
