The tuner itself can pass an IF signal just fine; therefore narrowing the problem to the other RF unit. I've even aligned the IF strip already, also on May 20.
If it doesn't work this time around, I will be checking voltages at multiple locations to see if I can pinpoint the trouble. But I'm optimistic that this RF unit will work. One thing for certain...I will find out later today.

So...I set the whole thing up (both chassis, woofer, and both tweeters) on the workbench and tried it out.
With the 690 set to band 1 (AM), I fed a 470 kc IF signal into the grid cap of the mixer tube.
Guess what...the signal came through loud and clear.
