    Hi,

    I recently acquired a U.S Military tube Amplifier for Single channel cylinder head temperature. The specification no is MIL-A-5746-A. I'll attach a few pictures of the device and specs for better understanding.

    Does anyone here have knowledge of this particular equipment or access to its schematics/manual?

    Thanks in advance.

    It seems to be very well provisioned with transformers.

    If it is from an old Military aircraft, search for preservation/restoration groups, they usually have a few bods who know every nut and bolt.

    That was meant more for the dragon, he seems to thing obsolete things like that are a national security risk and can't be talked about here. :) I've gotten many things like that from surplus stores over the years, before Ebay.

    Well, from the looks of the components used, it could be WWII device or early 1950. Finding people from those years is getting tough. So tubes have heaters, cathode and plate. Find the tube types get the pin out and this should be a start for reverse engineering. If it is flying equipment remember it is 400 Hz AC supply or 26 VDC. Good luck

    Here's a site that has 100's of military manuals that are public domain you can download for free:

    It may take some searching,but the manual with a schematic is out there.
