The IC 150 used (I believe) an LM301 in the high level portion and a
discrete circuit for the phono stage.

(Walt gets out his IC 150 service manual)

The ICs are:

LF356H FET Op amp - master gain stage
LM301AN Op amp - gain stage for the phono preamp
MC78L18ACP - Voltage regulators

So, partial credit.  (c:

The great thing about the IC 150 is that it was basically just a switchbox with one gain stage. Minimal.
