You are bidding for One pair GEC BL63 CV1102 amoked glass similar to 6SN7 direct replacement for 6SN7 with adapters (order if you want). One of the tubes has small glass debrids inside which doesn’t affect the sounding quality. The tubes were tested excellent on my Avo CT160 tube testers at the NOS range. The tubes sound wonderful on my SE 300B amplifier. What you see is what you get. Sold as is. No return. Please ask me anything if unsure. Thanks
P/S: The shipping fees in the listing is by regular mail (normally Vietnam post) taking from 12-25 days depending on buyers' local customs. To some regions, it can take even longer than that. Besides, Vietnam post is not always available to some countries in South America, Northern Europe or Africa. Please ask me before paying. If you want to use express shipping services like DHL, Fedex or UPS express taking 3-7 working days, you have to pay an extra of around $68.75. (For order over $1000, Express shipping service is a must. Please wait for the invoice to pay). Please let me know so that I can send you an invoice. If the item(s) purchased may not arrive or faulty, please don't hesitate to contact me before opening cases on ebay. I am willing to reach to a solution and make you completely satisfied. Thanks a million
