      Buy a contact cleaner from Vibroplex or make one yourself out of a
      sheet of 800 grit (fine) emory cloth doubled back on itself and glued
      and cut into strips - about a dozen from a 75 cent sheet of emory
      paper.

      Refinish the contacts yourself.

          Milt,

          $40.50 is the total price wo/ shipping. It includes replacing each post
          with a new contact, the contact spring, and a new sliding dash contact.
          I just called Vibroplex again to be sure.

          The real question for me is whether my post contacts really need
          replacing or if the fine grit cloth will work as well. I have used the
          grit in the past. I probably depends on the shape of the contact
          surface. All of my scratchy sounds are ONLY dot related.

          I have used Flitz metal polish before, but have reservations about it.
          Flitz is supposed to prevent further oxidation. Wouldn't that leave a
          film on it?

            Steve,
            I just looked at the Vibroplex page and the 40.50 price is for all the
            contacts. If all of yours are a wreck (??) and you need them replaced,
            that price doesn't seem too bad. However, David's suggestion is a good
            one. Those contacts are pretty thick and should last quite a number of
            years, even with heavy use. Getting the old ones smooth in the event a
            previous owner took a file to them (or other drastic measures). Good
            luck.

              I have not had experience with Flitz. I do use the contact cleaning
              strips (from Ebay) and they do a great job. I also installed a
              capacitor across my key contact posts and that has made a nice
              difference in the scratchy sound. I used a .01 microfarad cap from
              Radio Shack, and installed an "O" clip on the ends to keep it in
              place without having to worry about it dropping off during hook-ups.

              If the contacts are ruined, they can almost always be restored. What you need for that is a flat surface to put the fine crocus cloth on. (In my last email, I

                If the contacts are ruined, they can almost always be restored. What
                you need for that is a flat surface to put the fine crocus cloth on.

                (In my last email, I called what you need "emory cloth" by error, the
                abrasive is the same but when it is put on paper, it is caled emory
                paper and when it is on cloth it is called crocus cloth).

                Disassemble the bug, and CAREFULLY rub the contact (face down) in a
                figure-8 pattern being careful to press down on the center as to not
                round the contact (not really a problem as long as it is uniform).
                Another method is to cut a band of crocus cloth and wrap around your
                finger like a bandage and "massage" the silver (towards the finger) in
                a figure eight pattern.

                If it is extremely bad (which it isn't) use course crocus cloth for a
                few wipes, then medium for much more and then fine. The idea is to
                level the surface, then with the fine cloth to polish it.

                Clean with denatured (or rubbing) 90% alcohol. and let dry, then work
                on the other three contacts.

                Then when all is dry, polish with Flitz. It has an ingredient which
                bonds to the silver to prevent tarnish and is excellent for contacts.
                Clean by rubbing off with cotton pads or cotton puff. Do not use
                paper towel - or use cotton tipped swabs with caution - avoid scarring
                by directly hitting the wooden stick of the swab.

                Paper towel should not be used on any mirror surface, just glass
                cleaning microfiber, Turkish towels, cotton balls or fleece.

                  After a few months of all sideswiper sending, my bug has again caught
                  my attention. It is a 1953 Presentation, my favorite bug so far.

                  A friend told me Vibroplex will replace the contacts. I just called
                  Vibroplex and they said it is $40.50 to replace each contact on the
                  contact post, the contact spring, and the sliding dash contact.

                  Is that service worth the money? Or can I do a similar repair on my own?
