First, yes binaries to a text group if frowned on. Second, cross posting to
multiple groups is also frowned on. Ok enough ranting, now for your
A1 sections... The boxes as you call them are connected to ground. The ----v
along with the "box" is a standard audio connector notation...look here for
an example http://rocky.digikey.com/WebLib/CUI%20Inc/Web%20data/SJ-3513N.pdf
. The two ---v are the left and/or right side and the box is ground. Look at
the jack that plugs into it and you may understand.
As far as the transformer number...70500207. That is a part number for
whatever manufacture they use. I dont know what replacement to use...The
"domestic", "export", and "100v" are variances of the circuit. (either/or).
Depending on the parts of the tranformer you use you can use different input
voltages. These 3 senerios only show one half of the tranformer though and i
can't find the other half? As far as the other transformers, you only need
the 1 for input power.
From what you seem to know about electronics, this is probably a bit too
complex to start with. It looks like it even has some vaccum tubes in it. If
you want to learn, i would start with a simpler circuit. Good luck.
