Hi, we need an altitude alerter ADC P/N 540-22722-034 in operable condition, or just for parts. Please, contact me for more details Thanks

I do not have service manuals for the CVR.  But I wish to buy the schematic for the MK-12 D+TSO. I sent you PM.  

I have a lot of avionics service manuals and I am willing to trade schematics diagrams, or some pages, from the manuals for other schematics diagrams from other service manuals that I do not have and probably will need in the future. If you or your avionics tech are looking for a schematic diagram to fix a radio or ...

Can anyone email me the schematic (do not need service manual)? Thanks
