Jim,
I commented on your post years ago and refer to it all the time. Excellent!
And it's not just tubes but the entire hi fi chain can benefit from maintenance.
Not only to prevent anomalies but to get the best sound out of your system.
I've gotten a little lazy lately but usually once a year I dismantle, clean, tension and inspect every point of contact.
And I mean everything:
Binding posts, connectors, switches, controls, relays, fuses and their holders; power cords, receptacles (carefully), sockets, tubes, etc.
I even unscrew connections to capacitors and clean them. (Drained of course.)
It's amazing to see the grime that comes off sometimes.
In my case I can definitely hear a difference in sound for the better.
I inherited this habit watching my father who would always take things apart and clean them before bending to a service call. Of course we're talking the day of tube tvs and radios, analog tuning pots and channel switches. Motor brush contacts in furnaces, vacuum cleaners and washing machines.
Yes, besides my stereo, and sometimes to my wife's disappointment, I've kept some things going past their normal lifetime.
My two son's now also apply the "clean it first" process and have quickly resolved household and more frequently, computer issues at home, work and for their friends.
Sorry to get off topic, but I guess there was a time when universal maintenence was accepted. And admittedly, proprietary, sealed, and I guess digital parts make things less accessible to the DIY'r.
I sometimes wonder if there should be maintenance agreements built into warranties of the high end stuff much like there are for cars.
For non DIY's, perhaps a house call service might be a thought. Hmm... 😊
Cheers!

I know how to retention 8 pin sockets. How do you do those tiny 9 pin ones? If they get loose I usually just change them. Thanks.
But very carefully. Especially if the socket material is brittle as it may crack or chip.
The 9-pin Belton shown in the photo is easy to re-tension.
I've never had to use anything other than dental picks. I would imagine if there isn't much room to maneuver, one would almost have to resort to sewing needles or something similar that wouldn't accidentally break off between the socket wall and claws.
Cheers!
