Unless you have already done this, I would still go with Jim's recommendations.
Cleaning tube pins and sockets. And in this case ensure the socket contacts are tightened.
I've had instances where pin size varies. And if a pin is just slightly narrower or dirty, contact will be inferior until things warm up and expand. Such as you are experiencing.
Worth a try.
Cheers!
