Philco 118 alignment issue
#32

I do agree, but if I cannot get a peak at 1500KHz at all even with the high end AM band oscillator trimmer nut as far out as it will go what should I then do?

If I adjust the low end trimmer cap I can get 1500KHz to come in properly, but then 600KHz is way off and getting it close makes it to where 1500KHz is off by more than the trimmer can compensate for.

Thing is I remember it being quite accurate initially after the first alignment using the 1K resistor in place of the shadow meter coil and the AM band high side oscillator trimmer cap nut was in a different position. Then once the shadow meter coil was installed I did the initial alignment and all seemed good. Shortly thereafter I noticed the dial was off at 1000KHz and before removing and reinstalling the oscillator coil in order to get a peak at 1500KHz I then had to have the trimmer nut almost fully backed off.

Now that I removed and reinstalled the oscillator coil exactly how I removed it including lead dress I cannot get a peak at 1500KHz at all and with the trimmer cap nut all the way backed off as stated previous the best can do is 1492KHz.

I know something must have changed to cause that.

Ron, it would have been nice if the Philco alignment instructions had said what you did about the alignment. It would have saved many people a big headache.

That said if someone takes a properly working Philco 118 and checks the dial, couldn't they determine where the dial is off and have one of the dial makers make a dial that is correct or is it that one 118 will be off slightly differently than another 118?
