Details:

These are brand new SMT modules designed to replace the Heathkit 443-601 or 443-687 parts. These are notorious for bad connections over time. If your clock still has them, its time to replace them with the included high quality milled pin socket. Heathkit Clock Chip Replacement MK5017AAP HPN: 443-601, module for the 443-601.

The original kit used socket pin strips that were soldered in, and then the top band holding pins together is removed. One was the GC-1005 clock and other SB-634. There were actually two different Heathkit part numbers assigned to the Mistake MK-5017AAP device, because model's being designed at same time in engineering.
