Loose socket for 12AX7 tubes

Tube DIY Asylum

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

I have a Ming-Da MC7-R preamp which I barely use due to loose sockets for 12AU7 and especially 12AX7 tubes (I attach the picture). Sometimes it plays but sometimes one channel disappears due to loose contacts on the 12AX7 socket(s). I such a case, I have to rock a tube which produces a noisy sound but restores the contact for some time.

I wrote somewhere that some people tighten the sockets somehow (perhaps, using tooh picks).

Can I do the same or cure this problem in a different way, judging by the structure of the socket shown in picture?

Many thanks in advance.
