Unused Audio-Technica cartridge lead wires. While it depends on personal preference, these might be suitable for those who prefer a clear, well-defined sound. Audio-related products may also benefit from aging, and older items sometimes sound better. Please note that due to the current postal service, delivery on weekends and holidays is unavailable, and delivery times may take an extra 1-2 days or more. If you need the item urgently, please select a different shipping method. Important: ★ Due to shipping constraints, the lead wires will be shipped only in a zip-lock bag. If you require damage protection, please notify us before purchase, as additional shipping costs will apply. ★ The terminals of lead wires often use phosphor bronze or other copper alloys because they are less likely to cause poor contact during use compared to soft copper. Therefore, avoid forcing them in too hard, as this can easily break them at the base. (Compared to copper, these alloys are harder and less ductile, making them more prone to breaking under impact.) Use needle-nose pliers to gently insert the terminals, gripping the flat part of the tip, near the insertion point. The hole diameters at both ends of standard lead wires differ even when unused. Cartridges and headshells also have varying terminal sizes depending on the manufacturer, so be careful not to break them during installation. If it's too tight, slightly widen the opening before inserting. We have thoroughly inspected the items, and the terminals are less likely to break or deform during standard shipping compared to copper. We have also tested them by dropping them and stepping on them, and they should be fine unless intentionally damaged. In rare cases, there have been reports of items arriving broken or deformed. As stated in our profile, if you require a guarantee, please inform us of a shipping method change, as additional shipping costs will apply. If you do not notify us, we are very sorry, but we cannot provide any guarantee. #MC Cartridge MC Cartridge #Step-up Transformer Step-up Transformer #Turntable Turntable #Analog Record Analog Record #Cartridge Record #Tonearm Cartridge #Record Phono Equalizer #Phono Equalizer Tonearm #Audio Audio #Headshell #Lead Wire
