Locked SY-41CL back to life

[Geoff Quickfall]

Many discussions on this:

1. Frame work zebra stips
2. Non framework zebra strips
3. Wire wrapped
   

Wire wrap is best for CL conversion although my zebra working perfectly for years since beta testing. If sensitive then check screw posts for thread integrity.

Early 41C pre 1980 had nuts applying pressure to PCA for connection. Later these were removed and replaced with the rear shell lower screws compression method. The nuts were self tapping and not prone to reuses after service. They were replaced at HP service department with flat thick washers which then allowed the lower screws to take up the compression duty.
