I have a couple of weak 10BP4s lying around, but no urgent need to rebuild those or any others. If you're the nervous type, I guess you'd rush them off to Scotty before he closes his doors. An alternative is to hold onto them to give ETF some business when their operation starts up. Being a lazy type, I'm tempted to choose Door Number Two. It wouldn't matter to me if it took two or three years before ETF could accept orders. If lightning strikes and they never get off the ground, I haven't really lost anything -- and my weak 10BP4s just increased in value, since even a weak tube is better than a dud
