Help with my Carver CT-7

I have a Carver CT-7 Tuner/Preamp which I am generally happy with. Enough so to want to fix it. My problem is that both tape monitor switched (In/Out and Tape 1/Tape 2) no longer work. I have taken the unit apart several times, squirted DeOxit into the switches as well as I could (hard to do since openings don't really exist or can't be found by me) and exercised the switches many tens or hundred of times. Often the switches work for several days or weeks , then quit.
Anyone have any ideas that will keep the switches working much longer?

If Deoxit doesn't fix the problem then nothing will. Are you sure the cleaner is getting inside the switches? On some of those sealed switches I have had luck with spraying the cleaner from the shaft side; you will need to let it dribble slowly down the shaft into the switch body. Use a rag to absorb the excess. You may need to pull the front panel to gain access.
