Default Re: CRT Rejuvenation orientation

Contrarily, I used to do them face down so any debris would fall out of the way, though I do get your point. One thing I always found was that to get a lasting improvement the TV would need to be used immediately afterwards for a good while, and sometimes would make noises in the neck.
My experience of boosting tubes started with sets from around 1970 - I think earlier ones could have needed quite a different approach. My original tester was based on a Television design followed by a BK 467 which was very successful. However the age of reactivation came to an end in the late Eighties with the 30AX tubes - and woe betide anyone who tried to reactivate a Sony!
