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 4, black (white pointer line), unused. Size: Outer diameter approx. 14.5mm, height approx. 15.5mm, shaft hole approx. 6.4mm. Push-fit type (no side set screws) compatible with metric (mm) pots made in Japan & Asia. *Not compatible with USA pots with inch (imperial) specifications such as CTS. *If the fit is loose, please adjust by slightly widening the pot shaft. (This is common knowledge, so please be aware that it is not a reason for complaint) Images 5 & 6 are size reference images. Image 7 is a reference image for the listing's image. Please check the number of splines on your pot to determine compatibility. The right side of image 8 is a Japanese metric pot shaft. Use for repairs and customization 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" for an additional 50 yen, which is faster and has a tracking number. *If you need a large quantity, please contact me in the comment section.
