[TCML] A Pearson autopsy

[Finn Hammer <f-h@xxxx>]

All,

A Pearson autopsy.

The forensic lab has been working overtime to produce a report of the 
late Pearson 2100 Current Monitor.

Clad in copper, with it´s coat of green paint, it is a classy job, but 
laying all stripped on the cooling board, what meets the eye looks like 
something out of Kinrade´s estate:

Some of the potting removed reveals a high class strip wound core, 
lamination not more than 2 thou thick, and wound with some fancy nickel 
based metal.

There is nothing special about the main inductor winding, but the 
terminating resistive winding is attached to it with some odd carrier wires.
I have tried hard to describe all this in words, but failed miserably, 
so when the words count hit 1001 words, I fired up good old #DStudio, 
and did a rendering of the whole wiring layout:

With this layout in mind, this detail photo gives more meaning:

And even a poorly focussed closeup, where the termination wires can be 
glimpsed:

I have been unable to get access to one of these wires, to measure their 
thickness.

Hope this helps some....

Cheers, Finn Hammer
