Grid emission question

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

My tube preamp started acting up in the left channel. I tested the tubes (CJ ART, 5 6922's per channel) and one of the 6922's showed grid emission "reject" immediately on the meter. Replaced that tube and all is well.

Over the years I've had a few tubes short on me but never had a grid emission failure. I'd like to know what it means if someone could explain it in not too technical of terms. Thanks.
