Man its been years since I was here
Seem to have allot of breakdowns PLM20K44 amps
These units sit in racks and seem to die on their own and all are relatively new 
Any one else ?

Power supply failure?

On our Install side, we've seen a handful of them lose their processing settings over the last few years; just one day, it's reset itself to factory. D-series instead of PLM's, but they share most critical parts.

On the Production side (PLM's), we've had that happen once that I'm aware of.

All out failure, send to factory for repairs, no known cause?  I think maybe two out of ~ 200 over the last 5 years. We've got one with a module failure about to go out for repairs, but was manufactured in 2017. Our most recent purchase of PLM's that sees heavy use would've been manufactured early 2020; one of those lost its settings, but no failures. We use them to power Adamson E-Series, so we're not going easy on them either.

We have had 4 in the last few months
We also run Adamson E Series with ours

Curious, how has the warranty process been through Music Tribe? Have they been repairing the amps in a timely manner?

This issue was addressed in a recent-ish (last year or two) firmware update.

Good to hear...except I just (like three hours ago) reprogrammed an amp that had lost its firmware (though not its processing). Wouldn't boot, and a firmware check said it was running in SAFE mode (version 0.28). I've only seen this once before when a firmware update failed, and I highly doubt the client was attempting to update firmware on the unit (though I can't rule it out...just unlikely, as I'm not sure they're even aware of the existence of Lake). It WAS running 4.22 (Lake 7.0.6, I think?). I 'upgraded' (reloaded) the firmware, and the processing was still in place. Easy enough fix, but concerning none the less.
