One is too many...
Though I have heard from multiple sources that the 6GH8 isn't a bad tube at all, it's just that RCA chose to run the snot out of it as far as ratings are concerned. Fortunately for us the 6U8(A) is a suitable sub, so I just replace with those and never had a problem. I don't keep cases of 6GH8's around the house, but I have plenty of 6U8's.
