<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <BODY BGCOLOR="#FFFFFF"> Hi Marcel, I have had good luck, just using side cutters, crushing them, as long as it is the brittle ones. If it is the ones that are gummy on the tracker bar, then soak the tracker bar in gasolene, and scrape off the residue. It is pretty straight forward to replace the main tracker bar ones, just go in sequence. Try to get a diagram, of the ones for the centering mechanism, it saves the trial and error later. I have found that if you dip the end of the new tube in rubbing alcohol, to the depth you want to install them, they just slip on to that depth, and stop. It makes for a neat job. Oh yes, be sure to use the proper tubing, and not the clear plastic stuff. If the main run is lead, from the rubber at the transposing mechanism, check it out for corrosion. It corrodes from the inside out. It is just as easy to do the full job, in one trip. Any more questions feel free to ask. Good luck. John M.

The only question I have "for now", is the following:                What's the easiest way to remove the old tubing that seems to be stuck to the metal part of the action?I only have to replace the tubing behing the tracker bar. My customer told me that as she was adjusting the transposing mechanism, the player just went dead. After opening the tracker box, I noticed that all the tubes were broken. Is there an easy way to remove the old tubes? Thanks in advance for all your expertise. Marcel Carey, RPTSherbrooke, QC</BLOCKQUOTE> </BODY> </HTML>
