There is a Lexicon 224 with remote in my local Craigslist for 699$ The catch is powers up but doesn't pass audio. I have nothing to do with this but if someone was interested I'll forward the contact number. I also talke to Beamish electronic they said they have 95% of the parts to repair it Just thought I'd pass it on 🤔 Or you can look in Craigslist Tulsa Ok
A lot of the older lexicons (like the PCM series) have their A/D chips blow out. Those are rare, rare, rare... Did I mention rare? I don't know if the 224 has the same A/D, but I'd bet that it's a likely source of the problem if it is..

I'd really be careful. Some of the components (busted resistors, dried-out caps) can probably still be found if you look hard enough. The converters may have been old resistor-ladder Burr Browns, or even something older. It's been 20 years since I popped the hood on a 224. The converters will surely be rare and there could easily be something else ready to go kaplooie. The DSP logic was (I think) proprietary MSI (Medium Scale Integration), and there simply will be no more of those ever made. Even the computers holding the source code were sold to a junk dealer over 25 years ago.
I'd suspect that the best home for this 224 will be on the parts shelf of someone who already has a working unit. It's the equivalent of the old Chevy up on blocks--just in case.
