I hear hum through the headphones,
what do I do to fix it?
You may have a ground loop. To fix a ground loop,
try a ground loop isolator or an EbTech HumX. If
it’s low-level hum and noise, you can use Lo gain
to reduce it.
How does Valhalla work with (insert tube type
here)?
The short answer is, if it’s in the list in the front of
the manual, it’ll probably work fine. Beyond that,
you’re on your own. If the tube has a different
pinout, very bad things can happen. Best to stick
to the approved tube types.
But I don’t want to buy matched tube sets from
you!
That’s cool, you can buy them from anyone. The
6N1P and 6N6P are common tubes.
FAQ
Hey, I plugged Valhalla 2 into my (preamp, amp,
active speaker) and it makes popping noises/
turns off when I turn the Valhalla on or off.
Yes. Yes it does. Did you see the warning up
front, in the Operation section? You need to turn
Valhalla on and let its output stabilize before you
turn on your amp or powered monitors, and you
need to turn off the amp or powered monitors
BEFORE you turn off Valhalla.
Can I leave Valhalla 2 on all the time?
You can, but it will significantly shorten your
tubes’ effective lifespan (5,000 hours is about 200
days). For best life, we recommend you turn the
amplifier off when you’re not going to use it for
more than an hour.
It doesn’t turn on, what do I do?
Plug it in to a different AC socket. Ensure you are
not currently in a blackout. Then call us if it still
doesn’t turn on.
