I've made a lot of money just doing this and a few other simple cleanings to customer amps. They didn't know how simple yet important this is. They were expecting the need to replace tubes etc. although all of the components were fine. They were more than happy to just have to pay for my labor. I usually checked the bias too since I was already in the amp and that only takes about 5 minutes and did not charge anything for that. That kept them coming back. Really simple stuff that everyone with a tube amp should know how to do.
Not exactly. In a switching jack you have two leaf springs the have a 'dimple' stamped on one of them. They are pressing together and closing the electrical circuit between them when there isn't a plug inserted. When you put the plug in, one of the springs is pushed away by the tip of the plug, which separates the leaf springs and opens the circuit. So you need to get inside the chassis and clean the 'dimple' part of the jack by pushing it open and spraying it, then putting a piece of paper in the contact, letting the tension grip it, and pulling the paper out. You'll see a black line on the paper...that's the crap that was causing the bad connection. I used to use a burnishing file to clean these contacts but they'll remove any plating very easily. A strip of paper is just abrasive enough to polish and clean the contacts.
Thanks! I know exactly what part your talking about but have never cleaned them that way. I appreciate the new knowledge!

GuitarZ: Needed some noise to fill a break in a tune I'm recording. It was too quiet. Just happened to have some High Quality Dr Z Ghia noise to fill the void. "Heal Your Sound with Dr Z! It's not just a guitar tone prescription!"

GuitarZ: Must be great to be a skunk. Eating bird food about 10' from our sun room. I'm clapping and yelling. At best, it might have given me one "yea what?" look while continuing to dine. At one point, there were two skunks and two racoons.

easyed: Guitar Z, I encountered to ultimate garbage raiding combo once. We'd been having problems with the garbage cans being raided by raccoons for weeks. Late in the evening I heard rattling at the cans. I went out and found that he'd allied with a skunk. "OK"

GuitarZ: EasyEd - Someone at work topped us both. The inside of their car had been somewhat ransacked. They were blaming their son. They checked the video. It was a Bear! I'll stick with the racoons, skunks, foxes, and squirrels.

bigboki: In this age and time when everybody are struggling and especially S&Ms I am amazed to see that kind of ignorance. I am really sorry for your experience dear Dr Z but it is for the better. You don't want to do business with those kind of people anyway.

GuitarZ: Didn't want to restart the plumbing thread, so I figured I'd ShoutBox this. How the heck does cleaning the aerator on a faucet cause a leak to start under the faucet? Huh? Arggggh!!!!

The Bad Poodle Experience: well, Mike, it shouldn't have been the cause of a leak. double-check your work.

GuitarZ: I updated in the Plumbing thread that the Moen website says that a faulty aerator can cause a handle/base leak. Eiyy! I really don't understand how plumbing works. I was ready to double check all connections. But, the leaking stopped with cleaned Aerator.

GuitarZ: After finally training myself after 4 days to not bother trying to turn on the guest bathroom light because of the power outage, I just found myself bracing for the sound of the generator as I opened the garage door and it's now quiet. Power Back!
