Friends I'm having an issue with a Philco 46-420 (Hippo model) Code 121.

http://www.nostalgiaair.org/Resources/597/M0013597.htm

Tubes 7c7, 7a8, 7b7, 7c6, 50L6, 35z5.

It plays I do pick up the two major stations 750 & 680 in the ATL area but I get a lot of static much more than you would expect from a 6 tube radio. Volume works fine. I even took it outside to see if it made a difference and it didn't. Checked for in house issues like dimmers all was good

What I have done.
All tubes tested good and I even substituted spares I had and it made no difference
It was  restored filter caps and paper caps. Some were done by previous owner. Only the PF mica caps remain.
I did an alignment no problems in getting a tone and peaking the IF's

One thing I noticed C404A the bottom segment of the tuner section where one lead of the loop antenna attaches that you peak at 1500KC made no difference when you adjusted it. The problem?

Bad Mica cap I know it is rare but does happen.
 
I checked resistance of the IF's and they were fine also no problem peaking
Antenna coil resistance is good per print

I used the Philco Service manual and went through the sections and all check's and had tone where I was supposed too.
Not sure what to check next any ideas
