Nagra –
VPA
Installation of the tube protections
845 tubes run extremely hot, more than 300° C, it is mandatory to
install the tube protections for safety reasons. Even with the tube
protection, you should be careful not to get too close to the tubes and
especially to keep children away from the amplifier.
You should also make sure to keep any object or fabric (like curtains
for instance) away from the amplifiers to avoid any fire risk.
Gently slide the tube protection
down.
Make sure the screw holes are
placed above those of the VPA.
Using the hex
screwdriver provided put
the screws back in place
