Ok, lets be fair, I'm part of the NON-Tants movement. This probably
dates back to "Older than me" gear, that still "seems" to work OK with
those old Elcos. (So, freaking WHAT? I love to "print on tape" with
tube gear at average VU around zero dB - try that on Your 24/192)

Yamaha probably thought that these homeorgans they made are surpassed
by Casio made in the lifetime of the Tantalum capacitors.. little did
they know. Or maybe nobody realized, that this new, much smaller
technology has a totally different failure mode with short-circuit,
than previous.

Samppa, with a lots of speculation and no facts.
