David,
I would be interested in seeing a schematic on the wiring of the diode
array. I am not sure of how it goes - exactly. I'm not located near
a dedicated fax. I was wondering if it might not be too much trouble
to sketch the schemtic on some simple paint software and mail the bmp.
I would really appreciate this - Thanks.
