Probate court in Pennsylvania generally lasts 6 months to a year. Owner died in June of last year. Assume timeline is about right for the Krell case in whatever state is conducting it.
When a company is in probate court it is unlawful for anyone to disclose information therein. Probate court is a private matter and disclosure of any details could lead to additional delays and legal action to those that provide data during the probate process.
Gleaning information by any means is destined to fail. No one can tell you anything of significance. Much of what is discussed here (a lot to do about nothing) leads to the development of conspiracy theories and most who attempt to provide information are causing unnecessary angst for those that have equipment at Krell for repair.
Hence, no one should expect to receive any information on future intentions or even information on what assets are being held. It is unlawful for those that you are inquiring to give you details, but it would seem to me that those still affiliated with Krell are doing what they can to restart when this process ends.
Important to remember that a company can be bought while in the probate process and when that happens it becomes quite complex and thus, requires more time to finalize. It would seem feasible for them to be ripe for the taking by any number of large companies looking to expand on their offerings, and while Krell is not as widely known as McIntosh, they have a premium brand name.
