I had the same problem with tube cracking. Here's the solution: There is a tiny adjustment screw on the "disc" shaped thingie just below the suction arm. The screw faces the front and is easy to see if you take a look. Just loosen the screw and raise the arm slightly. Don't raise it too much or you'll be leaving solution on the record. Just takes a little trial and error. Re-tighten the screw and you'll be in business. I've gone several years now without cracking a tube.
Cracked record cleaning pick up tube
I have owned a VPI 16.5 recording cleaning machine for about 1 year. It has generally worked quite well, except for on two occasions, the pickup tube has cracked in the compression fit slot area.
My early speculation is that the issue may relate to the use of steam cleaning with simultaneous vacuum pickup. The pickup tube may thermally expand and subsequently crack within the compression fitting. I usually steam as one step in the cleaning process and I have been careful to minimize localized heating for fear of record warping. Thus, I am surprised if the tube would warm enough to crack.
Has anyone else had this mishap? Any alternative thoughts on the cause for the cracked pickup tube - they are not cheap!
