Philco 60 coil problems
#4

Hi Guys,

Thanks for all the suggestions. I just got her aligned, and so far so good. Here are a few things I noted:

1. The antenna coil for the police band is wound counterclockwise as seen facing the lugs, starting at the far end and ending at the lug end. I used 7 turns of 30 gauge wire.

2. The oscillator primary is wound clockwise as seen facing the lugs, starting at the far end and ended at the lug end. I used 19 wraps.

I scoped out the lugs and coils, and I can post notes if anyone is interested.

3. Someone replaced the first IF transformer with a stock 455 kHz can. They had bypassed the trimmers in the chassis and the trimmers in the can had enough adjustment to tune 460 kHz. It might be nice to have an original, but for the moment, it's working.

4. The set aligned nicely, except that I seem to loose a little selectivity at the high end of the frequency scale. Not a major problem, but I would be curious to hear some thoughts on this.

5. When I aligned the broadcast band, the dial for the police band was off by about 200 Hz. This is a later model 60, and there isn't a separate police band padder. I'm not sure there is much to do about this, or that it really makes an appreciable difference.

Thanks for the encouragement! The cabinet still needs work, and I'll post some pictures when it's done.

Roger
