ended up using just the speaker output from the mini system. I
disconnected one speaker and used the leads to feed the signal to
the caps, which I hooked up in series, a 15 Ohm resistor was
inserted as a dummy load. Its simple but effective, the layout is on page 3 of the schematic pdf file. These Sonicap Gen
1's are going to be tried out in my Phono stage output.
