Dieter,

Quick question -

Some of the pcbs require unique parts (you mention the DS-20 for the A-106,
for example)

I am going to ask my dealer here for some pcbs when i order, but how do i
know which pcbs require unique chips (and hence what to order in addition to
the pcbs)

I know this information is in the service manuals, but im not sure as i can
access them. And it would take a great deal of cross referencing to
determine the unique parts, just from the BOM.

Thank you,

Julian
