Comparing ye old signal generator with Kenwood 590s, we see 172.5 kc on Band A

I understand that 175 is the correct IF peak for this unit (Model 90 1-47)
Now, I know I'm doing something stupid, because I'm not getting signal thru the IF; the instructions say
"Remove grid clip from 1st det." (which I did), sig generator connected to said tube grid (thru a .1 cap), ground going to chassis; I just get weird noises....I did short stator and rotor of Var. Cap. RF section and have an AC voltmeter reading output of 2nd AF.
any suggestions?
-Simon
