Bob K,



I recall you had an Audio mixer board at one time and I would like to somehow get hold of one.



IIRC it was attached to a 25Pin PCB mount D-Sub connector, with 3-4 inputs and a single output.



This would be perfect for me since I plan to mix together the audio from an alternate radio plus the audio from an anunciating EFIS system and feed these to my intercom.



For PTT and MIC I plan to fit a 2 pole 2 position switch to select between Radio1 and Radio2.



Even if I could acquire the CCT and bare PCB that would be a great help.



Thanks,

Doug

   The board is still available at:



https://matronics.com/aeroelectric/Catalog/AECcatalog.html



The assembly manual and BOM is at:



http://www.aeroelectric.com/Catalog/AEC/9009/9009-700J.pdf



I'm told that a number of the parts cited from the Digikey

catalog have been replaced . . . you'll have to do a bit

of substituting. I have a list of the changes somewhere, I'll

try to find it an publish it on the List. I don't know when

I'll get to updating the BOM . . .
