Hi all, I've just recapped a Panasonic JU-570-2 with horribly leaking capacitors that ate a few traces on the spindle PCB. Now before assembling back the SDF-1001 I wanted to test and correct the spindle speed if needed. However the drive motor doesn't have the strobo patterns, so an alternate method must be used. Does anyone know if any of the programs on the test/demo disks can help? Images as many of you know are here: https://www.zimmers.net/anonftp/pub/cbm/demodisks/drives/index.html Does anyone know any test point on the spindle PCB? I think pin 6 of the motor controller IC could be a good place to look, but I figured out someone must already know how to do this task. Thanks in advance. Frank IZ8DWFReceived on 2025-02-12 15:00:01
