Cool. I've bought tubes from the first seller also (not IN18's) and they were good....that's a pretty fancy de-poisoner! You should consider putting that out there...I'd be interested...;-)
As for the continual failures, not sure at the moment what to suggest, certainly appears to be more than bad-luck....I've got a few of the recent Spectrums and haven't seen that behaviour...have you contacted Pete at all? He's usually more than happy to help troubleshoot...it's almost as if the tubes are being under-driven...
