Default Virtual battery operation ?

From the C1000 repair and user manual you press a button to opt for
battery
operation for no mains hum/ fridge spikes etc presumably


Shades of the 1920s and 30s, when battery operation was preferred by some
"audiophiles" of the day (because "mains sets hum"). But I thought that
attitude had died out decades ago, apparently not.

(if/after the
battery is charged off
the mains) or opt for mains power to the preamp. So I assumed the same
with
the C2000 but no battery or battery switch or anywhere obvious a missing
battery could be/have been connected/located.


I had assumed before that the battery was to back-up settings, hence my
comment about flash memory. If the VBO is intended to run the pre-amp, but
there is no battery, and no mains supply, I can only guess that in VBO mode
the pre-amp is entirely passive.

If it was not for Technics make and going by the heavy lump of metal, for
no
functional purpose, I would have said it was a con.


I'm not sure that just because it has a well-known name on the front you can
necessarily assume that it's not.
