Thank you for viewing. This is a lead wire for Fidelity Research FR cartridges. Please note that postal deliveries currently do not occur on weekends and holidays, and delivery times have been extended by 1-2 days or more, so it may take longer. If you are in a hurry, please choose a different shipping method. Important Notes: ★ Due to shipping constraints, the lead wires will be shipped only in a zip-lock bag. If you require damage insurance, please let me know before purchasing, as additional shipping costs will be required. ★ The terminals of lead wires often use copper alloys such as phosphor bronze because using ordinary soft copper can be too soft and cause poor contact during use. Therefore, avoid forcing them in too hard, as this can easily break them off at the base. (Compared to copper, these alloys are harder and less ductile, making them more prone to breaking under impact.) Use pliers to gently insert the terminal, gripping the flat part of the tip or the flat part near the insertion point. Even unused, standard lead wires have different hole diameters at each end. The diameter of the mounting part varies depending on the cartridge and headshell manufacturer, so be careful as you may break them during installation. If it's too tight, widen the hole slightly before inserting. I have checked them thoroughly, and the terminals are harder than copper, so it is unlikely that they will break or deform during normal postal delivery. I have tested them by dropping them and stepping on them with shoes, and they are usually fine unless intentionally damaged. Very rarely, there are cases where they are reported to be broken or deformed upon arrival. As stated in my profile, if you require a guarantee, you will need to pay for additional shipping costs, so please inform me of a shipping method change. If you do not make a request, I am very sorry, but I cannot offer any guarantee. Please understand. #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
