OK folks, please take the following with a grain of a kilo of salt.
I just bought a vintage Krell from a guy who works in the industry. We got to talking gear and shooting the breeze, and at some point I said good thing I can fix that Krell myself if it needs fixing, what with Krell being out of business and all. He said that's not the case, he knows folks at Krell and Krell is not out of business.
He was not interested in elaborating so I left it at that... No warranties expressed or implied.
