Hi,
Thanks for these schematics, very/very interesting.
I am an 'old' electronics engineer, been in software for a long time, so a bit rusty.
I would appreciate a little help.
Q1 What are the items marked X_COPPER in the image from 7607_G43, sheet 32, Intersil PWM controller?
They look like Gunn diodes but I think not, they are maked CPXX etc. I tried to upload image but fails, I'm new so maybe its me.
Q2 On sheet 30, VTT supply circuit shows resistors marked X_0R0402, what does that mean? Zero resistance??
Any help appreciated.
Will experiment with images later.
H
