No price negotiations. No bulk purchase discounts (shipping discounts). Please refrain from individual negotiations. Please purchase directly without waiting for a response. I aim to ship within 24 hours, so I will not comment until the item is shipped. Thank you for your understanding. *I do not issue receipts. Set of 3, DAVIES New 1510 Clone Type Color: Black, Deadstock, unused. Uses 1.5mm Allen wrench set screws to secure the shaft, so it can be used with both USA and Japanese potentiometers. *Allen wrench not included. Size: Outer diameter of the hat section is approximately 19mm, height is approximately 14.5mm. Shaft hole is approximately 6.5mm. *Image 5 is a reference image for size. Other items are not included. Use for repairs, customization, and dress-up of vacuum tube amplifiers, tube amplifiers, stereos, antique radios, audio equipment, guitar amplifiers, and effects pedals. Shipping is by regular mail (no tracking number), so delivery may take some time (even in Kanagawa and surrounding areas, it may take 3-4 days). *If you let me know in the comment section before purchasing, I can change to "Click Post" with faster delivery and a tracking number for an additional 50 yen. You can purchase directly without contacting me. I use recycled materials for packaging.
