I'm restoring this model and could use your help.

I've replaced paper and electrolytic capacitors and tested all tubes but I'm still having two key problems.

1.  When tuning the AM broadcast band, signals whistle and oscillate.  Fine tuning sometimes clears it up, but adjusting the treble control which moves a ferrite rod into (an IF coil?) usually does the trick.  What might be wrong here?

2.  The FM band is distorted, even with an external antena connected, through most of the dial but is clear on one or two strong stations.  Is it just in need of a tuning? 

Thank you for any help you can provide.
