Philco 52 - difficulty tuning
#1

Ok. I have taken apart this radio and revisited the schematic many times over.

It tunes very well for the Osc and 1st Det., using the signal generator blasting out through the speaker - loud and clear. However, although at one time i had weak stations, I cannot do the next steps and tune the stations.  i've looked at the coils and i cannot see a break in the wires.  I've gone over and over the schematic and i can't find my error. I have to assume i am grounding it somewhere but having checked the capacitor blocks and resistors so much, I need to take a breather and see if you guys can point me in the correct direction.  I don't know how i can put the signal generator on the antenna and hear it scream at 175Kh but not tune.  I can hear peaks throughout the 600 - 1400 range but no stations.  So signal comes out to the speaker but only a signal generated one.  Does this point to a coil that i need to inspect more closely?  Tnanks, Rich  tuning is always my weak spot.
