I need to know which Jantzen inductors should be used for my sda-srs..values are .4mh, 2.75mh and .7mh. I am looking at the parts express site. The 16mh I am buying from Solen

@wrich22a The chart above is for the 4th & 5th generation SDA only!, Yours are 3rd gen.
You'll need to measure the wire gauge & DCR of your inductors as theses value are not stated in the schematics. Get these wrong and you'll most likely change the speakers voicing most likely in a bad way.
Here is a link on how to measure inductor DCR and no your multimeter is not accurate enough.

Thanks for the info. I wonder if anyone has done the sda-srs , I was involved with this
about 8 years ago. I modified my SDA-SRS's with everything back then. except the inductors. I just retired and am trying to catch up with my unfinished projects. -
Not unless you count used circuit boards that have had all the previous components removed.
The Gimpod aftermarket circuit boards would be for later-generation speakers.
I suppose you could draw up the circuit, and have boards made. Not my first choice, however.

Is there a bare circuit board available?
