With the schematic, check the voltage test points.  If they are off I'd
start checking the Carbon Comp resistors which have a tendency to drift
"high"

A local club has asked me to look at returning an SB-301 / SB-401 pair to
operational condition.  The internal condition looks good and I don't see
any mods.
