The PHILCO Phorum

Hi, does this look like someone way over adjusted the slug on this 1st IF? I really dont know much about the slug adjustments being the rookie I am, but I have a little bit of experience with trimmer adjustments. This thing looks like its out about 1/2 inch past the can. This is the IF with the big mystery cap nobody on the other forum I visit was ever able to identify because of Philcos proprietary marking systems. I was thinking maybe that cap is bad and caused the person doing an alignment to way over compensate?

Philco 41-255

No, that is supposed to be like that. Chances are if you look underneath, there is another one on the bottom of the can also.

Nope, only one slug on that can, and it's on top. The other adjustment is a trimmer capacitor to the side of the slug.

Well, I was half right!

Thanks for the replies. Yes one slug and one trimmer on top.
I was just used to seeing it like this on my near identical 41-250 chassis so it looked like kind of radical adjustment to me.
Thanks!

Can't think of why anyone would make a screw that needlessly long, but then again, accountants were not running things way back when. A proper alignment will reveal all.

When it comes to those type of slugs they typically run more like your project radio than that last picture. Depends how its made, though. A peak may (probably) exist on either side of the coil as the slug passes through it so both could be correct.

Thanks for all the comments. Looks like I will be Ok then with this IF in place. The radio is currently going through reconditioning. I have replaced all the .003uf and larger caps and bad tubes and it still tunes stations. Now to try to fix the loose/worn band switch.

Much appreciated!
