[sdiy] Juno 106's 80017A structure

[sergio koval]

Hi to all...

My name is Sergio and I live in Barcelona (Spain).
This is my first post to the list... and sorry about my
poor english.

Recently, I made an archeological work by opening
an 80017A hibrid pack of an Juno 106, and inside it
I found two BA662 and one IR3109 chips (in SMD
format, of course).

I know that the BA662 can be partially replaced
with an CA3080... but I ignore if there are any
replacement (even on discrete mounting) for
the IR3109 filter chip.

There are any info about it ?

And, my next step will be to read the conecctions
between those 3 chips... then, if you knows that
somebody had made this diagram, please, tell me.

Very thankful...

Sergio
