Hi, I spoke to a Vadim from VacuumGlow a year ago about IN-18. He does pretty the same for his clocks - recovers NOS boxes with IN-18 from russian warehouses and old factories. He told me he rejects 80% of NOS tubes because of leaks or cathode poisoning. The remaining 20% which is used for clocks works with minimal failure rate. If the seal doesnt fail in first 30 years from manufacture, it will serve forever ;-) I guess the tubes on eBay are selected similar way (russian seller picks NOS boxes, selects good tubes and offers them on eBay), so if when you purchase tested IN-18s on eBay, they will very likely work without issues. Vadim from Pastindicator does the same with IN-14s and considers these tubes very good in quality - over 90% of NOS tubes is good. But despite this, he has boxes with thousands of duds ;-)
