Amplifone HV Schematic needed for revision A201012-02

Today I put a rebuild kit through an Amplifone HV Board

All vital parts were changed.

I had 1 part left over

It was a diode (CR4)

My board does not have one

It is revision A201012-02 board

My A201012 board has the diode

I am after a different diagram to this one please, IE: where the shaded area looks different and does NOT have CR4

Anyone have an early unmodified HV Schematic, so I can compare please?

Then I can easily convert my HV Board to the latest revision

Thank you

Still looking if someone has a diagram for this REV

In the meantime I traced out the PCB and components and came up with this (Very different)

Large diagrams
Version -01


Version -02


Does anyone know if the blue board is the same as this? IE version -02

IE: can I have a picture of the track side of a blue board please :D


I will document the procedure in changing this to a version -01 in due course
