[QuadList] Ampex Pinch Roller removal procedure

[Don Norwood]

Hi Buddy:

Excellent info from Larry and Chris.  I can add a suggestion to what Chris 
said about alignment.  I tighten the screws just to the point that the yoke 
will still move with some resistance.  Then manually press it against the 
capstan by applying pressure to the arm.  This will "seat" the roller 
against the capstan by positioning the yoke so the roller is perfectly 
aligned with the capstan.  Then release the arm and fully tighten the 
screws.  The yolk can move when tightened, so be sure to check the alignment 
again, and be certain to do it by hand, not by actuating the machine.  When 
you engage it by hand and use the light as Chris suggested, you can see if 
it is perfect or not.  If you engage the machine, the greater pressure 
exerted by the solenoid can compress the roller and hide the misalignment.
