I continue to have volume and tone pots hissing. I noticed if I press the one in question the hissing goes away so I tightened each pot but after a week of playing the hissing will return either on the same pot or another. Do anyone have suggestions to fix this on going issue. Thanks

In one of his amp maintenance videos Doc Z recommends loosening each pot, spraying behind it with DeOxit, and re-tightening the pot mounting nut. Same thing with all the jacks, be sure to do the input jack. And shoot a little into each pot and work it ten or twenty times to clean the wiper and contact surface inside. Tighten all ground connections and transformer mounting bolts. You also might pull each tube and reseat it. After time, these little things add up and noise often results.
Here's the video:

I wonder if a little LocTight on the threads would help secure it.

Yes that will help keep it tight but it won't prevent the corrosion that will eventually accumulate between dissimilar metals. Use Locktite 290 if you can get it. It is a "wicking type" that can be applied after tightening the nut. Otherwise use a drop of low-strength threadlocker like purple 222.

I think I’d only consider using loctite if I was touring and the amp got moved a lot. Annual or semiannual tightening should do the trick and I would not want to “lock down” anything even with the lower strength loctite unless I had to.

I got in the habit of using it from repairing other players amps. I occasionally found someone had previously over-torqued the nut and it was on the verge of stripping the thread, or maybe the thread was sloppy to begin with. Using threadlocker allowed me to secure the pot with a little less torque. Yes, changing the pot is better but if they still worked fine it saved the customer a little money. I don't recall one ever loosening after using it.
