delabs Notes

I am writing it here again, i was overwhelmed by the Cherokee Power Supply Design, which i saw in the Tek Logic Analyzer 1240, i was an R&D engineer and also worked on a DMM Option for 2235.

When i came first online i found that Cherokee is part of Lineage, today i find it is part of GE Energy.
