a) you can't measure the White Noise output with a DVM. For one, the noise
bandwidth is like 250Khz, and your DVM goes to 500Hz if you are lucky. Second,
by definition white noise has an ∗average value of zero volts∗. In fact, 1
'figure of merit' of just how "white" the white noise is, is to measure it with
an ∗averaging∗ (not RMS) meter. The closer to zero, the 'better the noise' :)

b) the S/H uses ∗pink noise∗ internally, through the switched jack. If you did
not wire the switching jack correctly, this would explain it.

c) do you have approx 8V pk-pk of Pink Noise at the Pink Out jack? If not, then
there is an error with the Pink Noise filter.
