If your coils are OK, short of oscillator misbehaving you should have it go through.

Thanks, I'll give it a go....

Finally got a chance to get back at this. Shot tone (460Khz) to RF grid good strong tone.
Same goes for 1st Det . Same for 1st I.F. .
It's the 2nd I.F. there is a amplitude issue. Tone yes but very weak.
At 1st Audio great tone and the same with the Dvr.
Question : The 2nd I.F. is weak but only when I connect signal directly to grid
of the 2nd I.F. The stages directly before 2nd I.F. (1st I.F.) I get a good tone. 
I'd think it wouldn't because of the 2nd I.F. stage was almost silent ? I'm going
to take a look at the 2nd I.F. layout for now.  
Thanks for all the assistance...
