SUBSTITUTES FOR 6SN7. This Shuguang Treasure CV181-Z tube is their premium export grade product and comes complete with special packaging (see photo). The tubes are accurately matched (see photo). The tubes are shipped from UK - no additional VAT to pay and no waiting - next day courier delivery (UK mainland only). INTERNATIONAL ORDERS welcome and fulfilled by eBays Global Shipping Program. I bought these amazing tubes intending to use them as substitutes for the 6SN7 tubes in my amplifier, but then decided to go in a different direction. The tubes are unused (except for brief testing to ensure that they worked properly, which I am pleased to say they do). The tubes construction features gold grid wires and a new internally coated black glass bottle. This unique HPCC coating is known as High Polymer Carbon Compound glass coating and is unique for its ability to reduce stray electron emission that can otherwise reflect off the glass. Shuguang also uses their new Super Alloy technology. Originally applied to aviation, aerospace, and military applications, this technology has been successfully used by Shuguang to accomplish directional solidification and single crystallization. This greatly improves the ability of electron emission and electron current stability. This new Shuguang Treasure series required additional parts selection quality control processes, improved vacuum techniques and additional burn-in time and testing. Extract from review of these tubes: The Shuguang Treasure Series CV-181Z tube is a unique take on the 6SN7 tube. Unlike a NOS CV-181 tube, the Shuguang CV-181-Z tube is a safe replacement in any 6SN7 circuit. It is not identical to the NOS CV-181 tube. However, compared to other 6SN7 tubes, the Shuguang Treasure CV-181-Z tube has a much larger ST style bottle. The beautiful ceramic base is over-sized as well, measuring 1 3/8 (35mm) in diameter. Many folks report that the sound quality rivals that of the best vintage 6SN7 tubes. The CV-181Z tubes construction features a ceramic base, gold grid wires and pins, and a new internally coated black glass bottle. This unique HPCC coating is known as High Polymer Carbon Compound glass coating and is unique for its ability to reduce stray electron emission that can otherwise reflect off the glass. Shuguang also uses their new Super Alloy technology. Originally applied to aviation, aerospace, and military applications, this technology has been successfully used by Shuguang to accomplish directional solidification and single crystallization. This greatly improves the ability of electron emission and electron current stability. This new Shuguang Treasure 6SN7 type required additional parts selection quality control processes, improved vacuum techniques and additional burn-in time and testing. This Shuguang Treasure 6SN7 type is their premium export grade. The sale is for one pair of matched tubes (two tubes, as shown in the photos). Please see my 100% positive feedback and buy with confidence. Thanks for looking!
