Philco 118 alignment issue
#24

As Mike sez. These sets (not just philco) typically are difficult to get dead on and track (having the exact frequency across the whole tuning range). Was just servicing an Emerson 706 from 1952. Cute midget AA5 set. Had a bad 2nd IF transformer (open). Replaced it, all caps, and a burned up 50c5 socket (it fell apart). Aligned the IF and all was fine. The oscillator has one adjustment for the high end of the band (1.6mc). After setting the osc at 1.6mc I tuned in a local station at 1060kc (KYW). Dial is on 1100kc. If I move the osc to put KYW at 1060 now 1600kc is like 1670. So KYW resides at 1100kc.

Now if your dial discrepancy keeps you up at nite, you have a lot of time on your hands, and are not easily frustrated look at your tuning condenser. Do the end plates on the rotor have slots cut into them?? If so these can be bent to change the tracking at various points across the tuning range. You can try bending those a bit but you may find that it's just another trade off.

>Also I removed the oscillator coil yesterday and it looks ok
I don't think I've ever had an oscillator coil change inductance all by it self. Typically on Philcos and others it usually works or not. Mica caps are another story but your frequency offset isn't all that much to start ripping in to the micas.
