Looking for a used but working TKS MX-300 Radio I currently have 3 of these I rotate to keep 2 working in the plane. Anyone have an old but WORKING one lying around they don't need/want anymore? I know many are upgrading and have no use for older radios. Offering $500-650 for a WORKING one, preferably one with a "dark" face on it to match my other two. See photos below. Alternatively, does anyone know where to get one repaired? I was calling around today and no one was interested in dealing with it anymore. They cite a paucity of parts, service manuals, and trained techs to work on the MX-300 radio anymore. Thanks - and yes, I know they are $3,500- $5,000 online for a newly factory-refurbished one - simply do not have that kind of $$$ for a 20+ year-old radio that is considered obsolete by most of the aviation community. Thanks for any offers or advice you can provide. I will certainly opt to REPAIR the ones I have if anyone knows where to send them.

I called a few places today (can't even remember if they were one of them) and got "the Heisman" from everyone! I will call tomorrow -- deeply appreciate the vector!

Please allow me to try the repair facility Hung recommended first, then I will get back to you one way or another. Thanks so much for taking the time and effort to respond and even add photos - that is why this club rocks. MM Mike Marra 1977 C-150M N714AJ Carlisle, PA.

I had an MX-385 (24V) radio in my former 152 and used to send it to TKM for service. Then one year they returned my radio unrepaired because they said it was out of their (sliding) window of serial numbers that they still worked on. They suggested that I send it to Bevan-Rabell. I didn't because I was about to sell my plane at that time (2017) and just put up with the problem (missing some segments on the LED number display).
