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: Reminds me of buying my Honda. When they tried to sell me the maintenance package, I said "Is your car not reliable?" Long story short my wife teamed up with the sales lady to buy the maint package. Never again!

capofirstfret: I've experienced tube rattle in two different amps that I've had. In both cases I bought the rubber rings from Eurotubes and it fixed it for me.

GuitarZ: Idiot! I wanted to put a little air on my Zoom H1's circuit board to clear out any residual Deoxit from spraying the input connector. Guess which can I picked up to spray. Yup! Not the air can.
