Yes, look at the schematic.

That's because my DVM is better than you DVM :)
Really, that's OK: I have a very wide-bandwidth DVM (Fluke 77). Set the trimpot (ising your DVM)
to 0.5V
When listening to the white noise

Yes, the manual is wrong about this (sorry!). These issues were discussed about 1 year ago (it's
in the archives).
