Minivation Posted February 15, 2021 Report Share Posted February 15, 2021 I'm afraid I don't have the manuals for the KA-134 in my library. I see that Texas Air Salvage has a handy pinout reference for it though: https://www.texasairsalvage.com/PinnoutPDFfiles/KA134.pdf If you really need the full thing, you could pay $20 and download it here: https://www.eflightmanuals.com/ITEM_EFM/SDETAIL_EFM.asp?mID=10852 I've used eFlightManuals for a few other manuals (King KY92, etc.) in the past and on all occasions they've delivered what I needed. 1 Quote Link to comment Share on other sites More sharing options...
Gary0747 Posted February 16, 2021 Author Report Share Posted February 16, 2021 I think it may be time to replace it. It is simply an input switching unit that feeds a Flightcom Sterio intercom with a Clearence recorder. The intercom works well and I would prefer not to replace it. My KA-134 is and old mechanical switching unit that feeds all the 500 ohm audio input together with no isolation amps. I was looking for a simple switching unit that has audio amps for each input for better isolation. Does anybody you know of make such a unit without all the intercom features?

jamesm Posted February 18, 2021 Report Share Posted February 18, 2021 Here is one that I had created in MS word on a windows pc a while back. looks kind of goofy in libre office text document. I found it helpful to me, when I take pictures of the receiving connector then picture label the pins/sockets with the signal names. This was my first attempts documenting the connectors. trying to figure out what works best.
