Radio Shack Intercom 43-3105

[George Columbo]

No power on indication when switched on. Power to input transformer, no
power out. Appears input transformer has open input winding. Input leads
are red, output leads are yellow. I have no idea what the output of this
transformer should be. Looking for shcematic, parts list or any other info
that may be helpful. Thanks in advance.
